Cytoskeleton consisting of microfilaments, intermediate filaments and microtubles.<br /><br /><strong>Centrosome:</strong> region where the cell's microtubles are initiated; in an animal cell, contains a pair of cetrioles (function unknown)<br /><br /><strong>Flagellum:</strong> locomotion organelle present in some animal cells; composed of membrane enclosed microtubleshttp://cellstructure.blogspot.com/2007/08/animal-cell.htmlnoreply@blogger.com (Taylor)0tag:blogger.com,1999:blog-5869701419801161603.post-1517135479250361806Fri, 17 Aug 2007 22:13:00 +00002007-08-17T16:29:58.818-07:00<strong>Nucleus:</strong> nuclear envelope, nucleolus, chromatin<br /><br /><strong>Central vacuole:</strong> prominent organelle in older plant cells; functions include storag, breakdown of waste products, hydrolysis of macromolecules; enlargement of vacuole is a major mechanism of plant growth<br /><br /><strong>Tonoplast:</strong> membrane enclosing the central vacuole<br /><br /><strong>Cytoskeleton:</strong> microfilaments, microtubles, intermediate filaments.<br /><br /><strong>Chloroplast:</strong> photosynthetic organelle; converts energy of sunlight to chemical energy stored in sugar molecules<br /><br /><strong>Plasmodesmata:</strong> channels through cell walls that connect the cytoplasms of adjacent cells<br /><br /><strong>Wall of adjacent cell<br /></strong><br /><strong>Rough endoplasmic reticulum<br /><br />Smooth endoplasmic reticulum<br /><br />Ribosomes<br /><br />Cell wall:</strong> outer layer that maintains cell's shape and protects cell from mechanical damage; made of cellulose, other polysaccharides, and protein<br /><br /><strong>Golgi apparatus<br /><br />Centrosome:</strong> region where the cell's microtubles are initiated; lacks centrioles in plant cellshttp://cellstructure.blogspot.com/2007/08/cell-sturcture.htmlnoreply@blogger.com (Taylor)0
