ગ્રેજ્યુએશન પછી નીચે દર્શાવેલી વિશેષ સ્કિલ્સ કે લોકેશન આધારિત નિર્ણયથી કમાણી અને પ્રેક્ટિસ બંનેમાં મલ્ટિપ્લાય ગ્રોથ મેળવી શકાય છે:

અલાઇનર્સ અને ડિજિટલ સ્માઇલ ડિઝાઇનિંગ (Aligners & Smile Designing): ટ્રેડિશનલ તાર (Braces) ની જગ્યાએ હવે ક્લિયર અલાઇનર્સનો ટ્રેન્ડ ખૂબ વધી રહ્યો છે.
ડેન્ટલ ઇમ્પ્લાન્ટોલોજી (Implantology): ગુમાવેલા દાંતની જગ્યાએ ઇમ્પ્લાન્ટ બેસાડવાની ટેકનિક શીખીને મોટો ગ્રોથ મેળવી શકાય છે. ગુજરાતમાં NRI પેશન્ટ્સ અને મેડિકલ ટૂરિઝમનો આમાં મોટો ફાળો છે.
માઇક્રો-એન્ડોડોન્ટિક્સ (Micro-Endodontics):** એડવાન્સ્ડ અને પેઇનલેસ રૂટ કેનાલ ટ્રીટમેન્ટ (RCT) ની માસ્ટરીથી પેશન્ટ્સનો સતત ફ્લો જાળવી શકાય છે.
તાલુકા અને સેમી-અર્બન વિસ્તારોમાં પ્રેક્ટિસ:** મેટ્રો શહેરોમાં સ્પર્ધા વધારે હોય છે, પરંતુ તાલુકા લેવલે કે વિકાસશીલ વિસ્તારોમાં ક્વોલિટી ડેન્ટલ કેરની આજે પણ ભારે અછત છે.

❓ વારંવાર પૂછાતા પ્રશ્નો (FAQs)

Q1: શું BDS કર્યા પછી જનરલ મેડિસિનની પ્રેક્ટિસ કરી શકાય?

જવાબ: ના, DCI ના નિયમો મુજબ BDS ડોક્ટર માત્ર મુખ અને દાંત સંબંધિત તબીબી સારવાર જ કરી શકે છે.

Q2: ગુજરાતમાં BDS એડમિશન માટે NEET પરીક્ષા ફરજિયાત છે?

જવાબ: હા, સરકારી કે પ્રાઇવેટ કોઈપણ ડેન્ટલ કોલેજમાં એડમિશન મેળવવા માટે NEET-UG પરીક્ષા આપવી અને ક્વોલિફાય થવું કાયદાકીય રીતે ફરજિયાત છે.

Q3: BDS પછી વિદેશ જવાનો સ્કોપ કેવો છે?

જવાબ: BDS પછી કેનેડા, ઓસ્ટ્રેલિયા, યુકે અને યુએસએ જેવા દેશોમાં સંબંધિત લાયસન્સિંગ પરીક્ષાઓ (જેમ કે NBDE, ADC, ORE) પાસ કરીને ડેન્ટિસ્ટ તરીકે સફળતાપૂર્વક સેટલ થઈ શકાય છે.

🎯 નિષ્કર્ષ (Conclusion)

BDS એ એક અત્યંત પ્રતિષ્ઠિત અને કમાણી કરાવી આપતું તબીબી ક્ષેત્ર છે. સફળતાનો આધાર માત્ર ડિગ્રી મેળવવા પર નથી, પરંતુ યોગ્ય ટેકનોલોજી અપનાવવા, પેશન્ટ સાથેના સબંધો જાળવવા અને સતત નવી સ્કિલ શીખવા પર રહેલો છે. જો યોગ્ય પ્લાનિંગ અને સાચા વિઝન સાથે આગળ વધવામાં આવે, તો ડેન્ટ્રીમાં ઉજ્જવળ ભવિષ્ય નિશ્ચિત છે.

Note 6

Seed

The ovules after fertilisation, develop into seeds.

A seed is made up of a seed coat and an embryo.

The embryo is made up of

a radicle
a plumule
an embryonal axis
Cotyledon: one (as in wheat, maize) or two cotyledons (as in gram and pea).

Structure of a Dicotyledonous Seed

Seeds of dicotyledon plants - such as grams, pea, all pulses

The outermost covering of a seed is the seed coat.

The seed coat has two layers,

the outer testa and
the inner tegmen.

The hilum is a scar on the seed coat through which the developing seeds were attached to the fruit.

Above the hilum is a small pore called the micropyle. - important while germination

Within the seed coat is the embryo,

- consists an embryonal axis and two cotyledons.

The cotyledons are often fleshy and full of reserve food materials. - required for vitality of seed in adverse conditions

At the two ends of the embryonal axis are present the radicle and the plumule

Endospermic seeds:

In some seeds the endosperm formed as a result of double fertilisation,

Eendosperm is a food storing tissue

Such seeds are called endospermic seeds.

Example: seeds of castor

Non-endospermous seeds:

In some seeds, the endosperm is not present in mature seeds

It gets utilised during development of seed and embryo

such seeds are called non-endospermous.

Example : bean, gram and pea

Structure of Monocotyledonous Seed

Generally, monocotyledonous seeds are endospermic

but some as in orchids are non-endospermic.

In the seeds of cereals such as maize the seed coat is membranous and generally fused with the fruit wall.

The endosperm is bulky and stores food.

The outer covering of endosperm separates the embryo by a proteinous layer called aleurone layer.

The embryo is small and situated in a groove at one end of the endosperm.

It consists of

one large and shield shaped cotyledon known as scutellum
and a short axis with a plumule and a radicle.

The plumule and radicle are enclosed in sheaths.

Plumule is enclosed with coleoptile.

Radicle is enclosed with coleorhiza.

Note 5

Fruit

The fruit - characteristic feature of the flowering plants.

mature or ripened ovary

developed after fertilisation.

If a fruit is formed without fertilisation of the ovary, it is called a parthenocarpic fruit. Example: banana.

Parts of fruit:

Generally, the fruit consists of a wall or pericarp and seeds.

The pericarp may be dry or fleshy.

When pericarp is thick and fleshy, it is differentiated into

the outer epicarp,
the middle mesocarp and
the inner endocarp.

In mango and coconut, the fruit is known as a drupe.

Drupe- it is a type of fruit.

They develop from monocarpellary superior ovaries.

Monocarpellary - flower has one single carpel in Gynoecium

Superior ovary - Hypogynous flower

They are one seeded.

In mango the pericarp is well differentiated into

an outer thin epicarp,
a middle fleshy edible mesocarp and
an inner stony hard endocarp.

In coconut which is also a drupe,

Outer layer - endocarp is skin of fresh coconut - generally green colored

the mesocarp is fibrous

Endocarp is the inner thick stony part of fruit

White layer of coconut or the coconut water should not be mistaken for endocarp

Standard 11

Morphology of flowering plants

Morphology of flowering plants| flower | NCERT short note| Best biology short note | standard 11

Note 4

Flower | Types of flower|Inflorescence | parts of flower

A flower is a modified shoot

Here, the shoot apical meristem changes to floral meristem.

Internodes do not elongate and the axis gets condensed.

The apex produces different kinds of floral appendages(floral parts) laterally at successive nodes instead of leaves.

When a shoot tip transforms into a flower, it is always solitary (single flower arises).

Inflorescence

The arrangement of flowers on the floral axis is termed as inflorescence.

2 major types of inflorescences are defined- according to on whether the apex gets developed into a flower or continues to grow,

– racemose and cymose.

In racemose type of inflorescences the main axis continues to grow,

the flowers are borne laterally in an acropetal succession

I.e. new flowers are on upper side of plant and old flower are beneath them

Growth is indefinite - doesn't terminate with flower

Racemose Inflorescence

Cymose Inflorescence

In cymose type of inflorescence the main axis terminates in a flower

Growth is limited - definite - terminate

The flowers are borne in a basipetal order

I.e. old flower is on top of the plant, whereas new ones grow below its level

The Flower

The reproductive unit in the angiosperms.

meant for sexual reproduction.

four different kinds of whorls arranged successively on the swollen end of the stalk or pedicel, called thalamus or receptacle.

These are calyx, corolla, androecium and gynoecium.

Calyx and corolla are accessory organs, while androecium and gynoecium are reproductive organs.

In some flowers like lily, the calyx and corolla are not distinct and are termed as perianth.

Parts of flower

1- Calyx

The calyx is the outermost whorl of the flower

the members are called sepals.

Generally, sepals are green, leaf like and protect the flower in the bud stage.

The calyx may be of 2 types

gamosepalous (sepals united) or

polysepalous (sepals free)

Parts of flower

2-Corolla

Corolla is composed of petals.

Petals are usually brightly coloured to attract insects for pollination.

Like calyx, corolla may also be

gamopetalous (petals united) or polypetalous (petals free).

The shape and colour of corolla vary greatly in plants.

Corolla may be tubular, bell shaped, funnel-shaped or wheel-shaped.

Aestivation:

The mode of arrangement of sepals or petals in floral bud with respect to the other members of the same whorl is known as aestivation.

The main types of aestivation are valvate, twisted, imbricate and vexillary

Valvate: sepals or petals in a whorl just touch one another at the margin, without overlapping, example: Calotropis.

Twisted: one margin of the appendage overlaps that of the next one and so on , example : china rose, lady’s finger and cotton

Imbricate: the margins of sepals or petals overlap one another but not in any particular direction , example : Cassia and gulmohur

Vexillary or Papilionaceous: there are five petals, the largest (standard) overlaps the two lateral petals (wings) which in turn overlap the two smallest anterior petals (keel) example: pea and bean flowers

3- Androecium

Androecium is composed of stamens.

Each stamen which represents the male reproductive organ

It consists of a stalk or a filament and an anther.

Each anther is usually bilobed and each lobe has two chambers, the pollen-sacs.

The pollen grains are produced in pollen-sacs.

A sterile stamen is called staminode.

Stamens of flower may be united with other members such as petals or among themselves.

When stamens are attached to the petals, they are epipetalous Example : brinjal

When stamens are attached to the perianth as in the flowers of lily - they are epiphyllous.

The stamens in a flower may either remain free (polyandrous)

or they may be united in varying degrees.

The stamens may be united into one bunch or one bundle (monoadelphous) as in china rose,

or two bundles (diadelphous) as in pea

or into more than two bundles (polyadelphous) as in citrus.

There may be a variation in the length of filaments within a flower, as in Salvia and mustard.

4- Gynoecium

Gynoecium is the female reproductive part of the flower

It is made up of one or more carpels.

A carpel consists of three parts namely
stigma, style and ovary.

Ovary is the enlarged basal part,
on ovary lies the elongated tube, the style.

The style connects the ovary to the stigma.

The stigma is usually at the tip of the style
Stigma is the receptive surface for pollen grains.

Each ovary bears one or more ovules attached to a flattened, cushion-like placenta.

Apocarpous: When more than one carpel is present, they may be free (as in lotus and rose)

Syncarpous: when carpels are fused, as in mustard and tomato. After fertilisation, the ovules develop into seeds and the ovary matures into a fruit.

Placentation: The arrangement of ovules within the ovary is known as placentation.

The placentation are of different types namely,
marginal, axile, parietal, basal, central and free central.

In marginal placentation the placenta forms a ridge along the ventral suture of the ovary and the ovules are borne on this ridge forming two rows, example : pea.

Marginal placentation

When the placenta is axial and the ovules are attached to it in a multilocular ovary (ovary with many chambers-locules), the placentaion is said to be axile, example : china rose, tomato and lemon.

Axial placentation

In parietal placentation, the ovules develop on the inner wall of the ovary or on peripheral part. Ovary is one-chambered but it becomes two chambered due to the formation of the false septum, e.g., mustard and Argemone.

Perietal placentation

When the ovules are borne on central axis and septa are absent, as in Dianthus and Primrose the placentation is called free central.

Free central placentation

In basal placentation, the placenta develops at the base of ovary and a single ovule is attached to it, as in sunflower, marigold.

Basal placentation

Types of flowers

>>On basis of presence of androecium and gynoecium in a flower

1. When a flower has both androecium and gynoecium, it is bisexual.

2.A flower having either only stamens or only carpels is unisexual.

>> In symmetry, the flower may be actinomorphic (radial symmetry) or zygomorphic (bilateral symmetry).

1. When a flower can be divided into two equal radial halves in any radial plane passing through the centre, it is said to be actinomorphic, e.g., mustard, datura, chilli.

2. When it can be divided into two similar halves only in one particular vertical plane, it is zygomorphic, e.g., pea, gulmohur, bean, Cassia.

3. A flower is asymmetric (irregular) if it cannot be divided into two similar halves by any vertical plane passing through the centre, as in canna.

>> on basis of number of floral parts

A flower may be trimerous, tetramerous or pentamerous when the floral appendages are in multiple of 3, 4 or 5, respectively.

>> Flowers with bracts-reduced leaf found at the base of the pedicel - are called bracteate (example- Bougainvillea) and those without bracts, ebracteate.

>> Based on the position of calyx, corolla and androecium in respect of the ovary on thalamus, the flowers are described as hypogynous, perigynous and epigynous.

1. In the hypogynous flower the gynoecium occupies the highest position while the other parts are situated below it.

The ovary in such flowers is said to be superior

e.g., mustard, china rose and brinjal.

2. If gynoecium is situated in the centre and other parts of the flower are located on the rim of the thalamus almost at the same level, it is called perigynous.

The ovary here is said to be half inferior

e.g., plum, rose, peach.

3. In epigynous flowers, the margin of thalamus grows upward enclosing the ovary completely and getting fused with it, the other parts of flower arise above the ovary.

Here, the ovary is said to be inferior as in flowers of guava and cucumber, and the ray florets of sunflower.

The Leaf | Types of leaf|Venatian | Modification of leaves

Characters of leaf

The leaf is a lateral, generally flattened structure borne on the stem.

develops at the node

bears a bud in its axil.

The axillary bud later develops into a branch.

Origin of leaves

Leaves originate from shoot apical meristems and are arranged in an acropetal order

Acropetal- new leaf on top , old leaves at base

They are the most important vegetative organs for photosynthesis.

Parts of leaf

A typical leaf consists of three main parts: leaf base, petiole and lamina

1. Leaf base

The leaf is attached to the stem by the leaf base

At base, it may bear two lateral small leaf like structures called stipules.

In monocotyledons, the leaf base expands into a sheath covering the stem partially or wholly.

In some leguminous plants the leaf base may become swollen, which is called the pulvinus.

2. Petiole

It help hold the blade to light.

Long thin flexible petioles allow leaf blades to flutter in wind, thereby cooling the leaf and bringing fresh air to leaf surface.

3. Leaf blade / Lamina

The lamina or the leaf blade is the green expanded part of the leaf with veins and veinlets.

There is, usually, a middle prominent vein, which is known as the midrib.

Veins provide rigidity to the leaf blade

Parts of leaf

They act as channels of transport for water, minerals and food materials.

The shape, margin, apex, surface and extent of incision of lamina varies in different leaves.

Venation

The arrangement of veins and the veinlets in the lamina of leaf is termed as venation.

Reticulate Venatian: the veinlets form a network

Leaves of dicotyledonous plants generally possess reticulate venation

Parallel Venatian: the veins run parallel to each other within a lamina.

Parallel venation is the characteristic of most monocotyledons.

Types of Leaves

A leaf is said to be simple, when its lamina is entire or when incised, the incisions do not touch the midrib.

When the incisions of the lamina reach up to the midrib breaking it into a number of leaflets, the leaf is called compound.

A bud is present in the axil of petiole in both simple and compound leaves, but not in the axil of leaflets of the compound leaf.

The compound leaves can be of two types

In a pinnately compound leaf a number of leaflets are present on a common axis, the rachis, which represents the midrib of the leaf

Example : Neem

In palmately compound leaves, the leaflets are attached at a common point, i.e.,bat the tip of petiole

Example: silk cotton.

Phyllotaxy

Phyllotaxy is the pattern of arrangement of leaves on the stem or branch.

This is usually of three types – alternate, opposite and whorled.

In alternate type of phyllotaxy, a single leaf arises at each node in alternate manner

Example : china rose, mustard and sun flower plants.

In opposite type, a pair of leaves arise at each node and lie opposite to each other

Example : Calotropis and guava plants.

If more than two leaves rise at a node and form a whorl, it is called whorled

Example: Alstonia.

Modifications of Leaves

Leaves are often modified to perform functions other than photosynthesis.

Support: They are converted into tendrils for climbing as in peas

Protection: They are converted into spines as in cacti

Food storage: The fleshy leaves of onion and garlic store food.

In some plants such as Australian acacia, the leaves are small and short-lived. The petioles in these plants expand, become green and synthesise food.

Predation: Leaves of certain insectivorous plants such as pitcher plant, venus-fly trap are also modified leaves.

Note 1

The Root | Regions of root| Modification of root

Root of dicotyledonous plant

Direct elongation of radicle - formation of primary root

The roots grow inside the soil

It has lateral roots of several orders - referred to as secondary, tertiary etc roots

Primary root+ its branches - tap root system

Example : mustard plant

Root in monocotyledonous plants

Primary root- short lived

Primary root replaced by a large number of roots

Originates from the base of the stem

This forms fibrous roots .

Example : wheat plant

Adventitious roots

Roots that arise from parts of plant other than radicle

Example : grass, Monstera, banyan tree

Functions of root system:

Absorption of water from soil

Absorption of minerals from soil

Providing anchorage to parts of plant

Storing nutrients

Synthesis of growth regulators

> Regions of the Root

Root cap

Situated on the apex of the root

It is a thimble like structure

Function: protects tender apex of the root -when it makes way through soil

Region of meristematic activity

Situated at few millimeters above root cap region

Cells of this region are very small, thin-walled and with dense cytoplasm

They get divided repeatedly

Region of elongation

Cells proximal to the region of meristematic activity form region of elongation

They undergo rapid elongation and enlargement

It is responsible for the growth of root in length.

Region of maturation

It is proximal to region of elongation

Cells of elongation zone gradually differentiate and mature. - this way region of maturation is formed

Root hair

Made out of epidermal cells from region of maturation

They form very fine and delicate, thread-like structures - called as root hairs

Function: absorb water and minerals from soil

> Modification of Root

Root in some plants change their shape and structure

They become modified to perform functions other than absorption of water and minerals

They are modified for support, storage of food and respiration

Modification for storage of food:

Tap roots of carrot, tap roots of turnip and adventitious roots of sweet potato

They get swollen and store food.

Modification for support

Prop roots - Banyan tree- hanging structures that support the tree

Stilt root - roots coming out of the lower nodes of the stem - maize and sugarcane

સ્તંભમૂળ

Pneumatophores - plants growing in swampy areas - many roots come out of the ground and grow vertically upwards - help to get oxygen for respiration- Rhizophora

Note 2

The Stem | Modification of stem

The stem is the ascending part of the axis bearing branches, leaves, flowers and fruits.

It develops from the plumule of the embryo of a germinating seed.

The stem bears nodes and internodes.

Nodes: The region of the stem where leaves are born are called nodes.

Internodes are the portions between two nodes.

The stem bears buds, which may be terminal (at top) or axillary (in the corner of two branches at node)

Stem is generally green when young

Later often stem becomes woody and dark brown.

Functions of the Stem

The main function of the stem is spreading out branches bearing leaves, flowers and fruits.

It conducts water, minerals and photosynthates (compounds formed by photosynthesis process)

Some stems perform the function of storage of food, support, protection and of vegetative propagation.

Modifications of Stem

The stem may not always be typically like what they are expected to be.

They are modified to perform different functions.

> Storage of food

Underground stems of potato, ginger, turmeric, zaminkand, Colocasia are modified to store food in them.

They also act as organs of perennation (ability to survive in cold-dry conditions) to tide over conditions unfavourable for growth.

> Support

Stem tendrils which develop from

axillary buds, are slender and spirally coiled

They help plants to climb such as in gourds (cucumber, pumpkins, watermelon) and grapevines.

> Protection

Axillary buds of stems may also get modified into woody, straight and pointed thorns.

Thorns are found in many plants such as Citrus, Bougainvillea.

They protect plants from browsing animals.

> Photosynthesis

Some plants of arid regions (dry weather regions) modify their stems into flattened (Opuntia), or fleshy cylindrical (Euphorbia) structures.

They contain chlorophyll and carry out photosynthesis.

> Spread and vegetative propagation

Underground stems of some plants such as grass and strawberry, etc., spread to new niches and when older parts die new plants are formed.

In plants like mint and jasmine a slender lateral branch arises from the base of the main axis and after growing aerially for some time arch downwards to touch the ground.

A lateral branch with short internodes and each node bearing a rosette of leaves and a tuft of roots is found in aquatic plants like Pistia and Eichhornia.

In banana, pineapple and Chrysanthemum, the lateral branches originate from the basal and underground portion of the main stem, grow horizontally beneath the soil and then come out obliquely upward giving rise to leafy shoots.

NEET UG 2024: important high scoring topics to get full marks in biology

2023-09-29T11:30:00.007+05:30

Which topic of biology to read to crack NEET? How to prepare BIOLOGY for NEET?

NEET UG 2024: important high scoring topics to get full marks in biology

The date of NEET UG 2024 has already been announced. Along with this, the preparation of all the students will also be encouraged. The NEET exam is conducted once a year, and through it students get admission in undergraduate courses in the medical field. So this exam is very important for the students who want to advance in the medical field.

NEET UG 2024 DATE

Students are working day and night for NEET preparation. Because every year lakhs of students appear in NEET UG exam. But medical seats are very limited. So NEET exam becomes very competitive.

If you want to get admission in medical field through NEET UG exam then it becomes necessary to do smart work along with hard work. We have to work hard, but in such a way that we get full benefit from the hard work we do.

The NEET paper has three main sections: physics, chemistry and biology. Out of these three, it can be said for biology that marks can be obtained sitting in it. You just have to understand how to prepare. In this article we will tell you the topics from NEET UG exam syllabus which are very important. A good understanding of this topic guarantees that your biology marks will go up a lot.

NEET UG 2024 SYLLABUS

Important high scoring topic for biology - NEET

You all must know that NEET syllabus is completely NCERT syllabus. In that too, especially for biology, only and only NCERT book is enough. So which chapter and unit are important among them are explained below.

Standard 11- biology most important chapter

1. In Unit 1 classifications are encountered.

One of the most important chapter of Unit 1 - "plant kingdom"
'Plant kingdom' chapter is in a way the foundation of botany from the entire NEET BIOLOGY Syllabus. That means if this chapter has been well understood - then there will be no confusion in other topics of botany.

2. Unit 3 is the key to understand whole basics of NEET biology.

Because it contains detailed information about the cell. And cells are important for both botany and zoology.

Understanding and concept of these two chapters "Cell: the unit of life" and "cell cycle and cell division" is very necessary. Many conceptual questions of NEET can be asked from these two chapters.

3. Unit 4 is part of the botany syllabus. It explains the important processes taking place in plants.

"Photosynthesis in higher plants" from this chapter plant cycles etc. are very important topics. Do clear its concept. Because very twisted questions can be asked from it.

"Respiration in plants" - Questions of about 3 to 5 marks are asked from this chapter of botany as well. Do clear the concept of aerobic - anaerobic respiration. Also keep revising all cycles.

4. There are very important chapters in the last unit - unit 5 of class 11. Of which there is much to remember.

"Neural control and coordination" - every year almost 4 to 5 questions are asked from this chapter.

"Chemical coordination and integration" - There are many important topics about hormones from this chapter. It is necessary to keep revising about it. Because questions are asked about different hormones and students get confused.

Standard 12- biology most important chapter

1. In Unit 6 basics of zoology અને botany are covered in chapters. Chapters of reproduction are of most importance

"Reproduction in flowering plants" - Basic concept questions are asked from this chapter. So, understand every line of NCERT BIOLOGY.

Every year many conceptual questions are asked about male and female reproductive system from the unit "Human reproduction". Questions with images can also be asked from them.

2. Unit 7 in which genetics is covered - it is one of the most important and interesting unit.

Concept of genetics which is given in "Principles of inheritance and variation" chapter. Many topics in this chapter require a deeper understanding. So understand all the topics of this chapter carefully. Questions of 6 to 7 marks can be asked from them.

Important topics like DNA - RNA which are in "Molecular basis of inheritance" are very important concepts. There are 7-8 marks questions about it in NEET exam. So students should understand this chapter specially.

3. Both chapters of biotechnology of Unit 9 are very important.

Many topics like Recombinant DNA processing and RNAi are important from this unit. Once you understand this unit carefully, you will never have to worry about it. But it is very important to understand each and every concept of biotechnology thoroughly.

4. "Ecosystem" of Unit 10 is of special importance as preparation for NEET. At least 2 questions are asked every year about nutritional cycles and succession. Apart from that, the energy pyramid topic is also very important.

All these topics have been told to you but what should be the technique to read them?

Tricks to get full marks in NEET UG biology

First read NCERT completely for NEET preparation. Understand each line of NCERT in depth. You will get to see all NCERT concept videos on our YouTube channel. You can also understand it

Once the topic is understood, it should not be left aside. It is necessary to revise all topics and chapters read before at least once every month. Only then that concept will fit in your mind.

Making notes of NCERT topics is also very helpful. You will find many notes on our website. Also, new notes are posted every day, so you should keep checking this website.

We cannot directly check whether the concept has been understood or not! So keep solving MCQs. The more you solve MCQs, the more your confidence will increase. You will realize your mistakes. Along with the concept, a free test of that concept is also placed on this website. You can see it too.

To know which is the best book for solving MCQ according to each chapter, read the article below.

Note 13

Seed developement

seed is the final product of sexual reproduction in angiosperms.

Seed can be described as a fertilised ovule.

Seeds are formed inside fruits.

A seed typically consists of

seed coat(s),
cotyledon(s) and
an embryo axis.

> The cotyledons of the embryo

simple structures,
generally thick and swollen due to storage of food reserves (as in legumes).

Mature seeds may be non-albuminous or ex-albuminous.

Non albuminous seeds have no residual endosperm - it is completely consumed during embryo development - example: pea, groundnut.

Albuminous seeds retain a part of endosperm - it is not completely used up during embryo development - example: wheat, maize, barley, castor.

In seeds of black pepper and beet, remnants of nucellus are also persistent.

This residual, persistent nucellus is the perisperm.

> seed coat

Integuments of ovules harden and form tough protective seed coats.

The micropyle remains as a small pore in the seed coat.

This facilitates entry of oxygen and water into the seed during germination.

> seed maturation

As the seed matures, its water content is reduced

seeds become relatively dry (10-15 % moisture by mass).

The general metabolic activity of the embryo slows down.

The embryo may enter a state of inactivity called dormancy.

If favourable conditions - adequate moisture, oxygen and suitable temperature - are available, seeds germinate.

As ovules mature into seeds, the ovary develops into a fruit,

the transformation of ovules into seeds and ovary into fruit proceeds simultaneously.

The wall of the ovary develops into the wall of fruit called pericarp.

The fruits may be fleshy as in guava, orange, mango, etc.,

Or the fruits may be dry, as in groundnut, and mustard, etc.

Many fruits have evolved

mechanisms for dispersal of seeds. Recall the classification of fruits and

their dispersal mechanisms that you have studied in an earlier class.

Is there any relationship between number of ovules in an ovary and the number of seeds present in a fruit?
- yes, Ovules after fertilization, mature into the seed and the ovary develops into a fruit. So if all ovules present in an ovary are fertilized, the number of seeds present in the fruit will be equal to the number of ovules present in the ovary.

In most plants, by the time the fruit develops from the ovary, other floral parts degenerate and fall off.

However, in some - the thalamus also contributes to fruit formation. Example: in a few species such as apple, strawberry, cashew, etc. Such fruits are called false fruits.

Most fruits however develop only from the ovary - they are called true fruits.

Fruits are the results of fertilisation - in most of the species.

Some fruits develop without fertilisation. Such fruits are called parthenocarpic fruits. Example: Banana.

Such fruits are seedless.

Parthenocarpy can be induced through the application of growth hormone

> advantages of seeds to angiosperms

reproductive processes such as pollination and fertilisation are independent of water, seed formation is more dependable on water.
Seeds have better adaptive strategies for dispersal to new habitats and help the species to colonise in other areas.
As they have sufficient food reserves, young seedlings are nourished until they are capable of photosynthesis on their own.
The hard seed coat provides protection to the young embryo.
Being products of sexual reproduction, they generate new genetic combinations leading to variations.

> advantages of seeds to human

Seed is the basis of our agriculture.

Dehydration and dormancy of mature seeds are crucial for storage of seeds

Seeds can be used as food throughout the year and also to raise crop in the next season.

Can you imagine agriculture in the absence of seeds, or in the presence of seeds which germinate straight away soon after formation and cannot be stored? -
It is disadvantageous if the seeds can't be stored. It is because seeds if sowed in conditions which are unfavorable to the crop, they will not be able to germinate efficiently. Even if germination occur and the conditions are unfavorable for the growth of the plant, then this would lead to post harvest losses. Therefore, it is difficult to imagine agriculture without seeds or with those seeds that can germinate instantly.

How long do the seeds remain alive after they are dispersed?

The period for which the seeds remain alive after they are dispersed again varies greatly.

In a few species the seeds lose viability within a few months.

Seeds of a large number of species live for several years.

Some seeds can remain alive for hundreds of years.

There are several records of very old yet viable seeds. The oldest is that of a lupine, Lupinus arcticus excavated from Arctic Tundra. The seed germinated and flowered after an estimated record of 10,000 years of dormancy.

A recent record of 2000 years old viable seed is of the date palm, Phoenix dactylifera discovered during the archeological excavation at King Herod’s palace near the Dead Sea.

Can you think of some plants in which fruits contain very large number of seeds?
Orchid fruits are one such category and each fruit contain thousands of tiny seeds.
Similar is the case in fruits of some parasitic species such as Orobanche and Striga.

Note 12

Endosperm developement| Embryo development

POST-FERTILISATION : STRUCTURES AND EVENTS

Following double fertilisation, many events occur

endosperm development
embryo development
maturation of ovule(s) into seed(s)
Maturation of ovary into fruit

These events are collectively called as post-fertilisation events.

Double fertilization notes

Endosperm developement

The primary endosperm cell divides many times - forms a triploid endosperm tissue.

The cells of this tissue are filled with reserve food materials.

They are used for the nutrition of the developing embryo.

This way Endosperm development precedes embryo development.

Commonly, in endosperm development, the PEN (Primary Endosperm Nucleus) undergoes successive nuclear divisions -- give rise to free nuclei.

This stage of endosperm development is called free-nuclear endosperm.

After that cell wall formation occurs - the endosperm becomes cellular.

The number of free nuclei formed before cellularisation can be different in different plants.

The coconut example:
Coconut water from tender coconut is free-nuclear endosperm (made up of thousands of nuclei)
The surrounding white kernel is the cellular endosperm.

Endosperm can be completely consumed by the developing embryo before seed maturation - example: pea, groundnut, beans

Endosperm may persist in the mature seed and be used up during seed germination - example: castor and coconut

Embryo development

Embryo development is also termed as embryogeny

Embryo develops at the micropylar end of the embryo sac where the zygote is situated.

Most zygotes divide only after certain amount of endosperm is formed. - adaptation to provide assured nutrition to the developing embryo.

The seeds differ greatly but the early stages of embryo development (embryogeny) are similar in both monocotyledons and dicotyledons.

the stages of embryogeny in a dicotyledonous embryo

The zygote gives rise to the proembryo and subsequently to the globular, heart-shaped and mature embryo.

A typical dicotyledonous embryo

It has an embryonal axis and two cotyledons.

The portion of embryonal axis above the level of cotyledons is the epicotyl,

Epicotyl terminates with the plumule or stem tip.

The cylindrical portion below the level of cotyledons is hypocotyl.

Hypocotyl terminates at its lower end in the radicle or root tip.

The root tip is covered with a root cap.

Embryos of monocotyledons

It has only one cotyledon.

In the grass family the cotyledon is called scutellum

Scutellum is situated towards one side (lateral) of the embryonal axis.

At its lower end, the embryonal axis has the radical and root cap enclosed in an undifferentiated sheath called coleorrhiza.

The portion of the embryonal axis above the level of attachment of scutellum is the epicotyl.

Epicotyl has a shoot apex and a few leaf primordia enclosed in a hollow foliar structure, the coleoptile.
