Cell Structure and Functions

Check us out at http://www.tutorvista.com//videos
This BioCoach module is designed to help you review cell structure. You will find information about the structure of prokaryotic cells and the structure of eukaryotic cells, with a focus on the latter. Animations and interactive activities will enrich your review experience in a dynamic way. This module is designed to be a supplement to, but not a replacement for, your textbook and classroom notes. You can test your understanding of morphology and function of the key structural components described by using the Self-Quiz at the end of the module
The common features of prokaryotic and eukaryotic cells are:
1. DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes

2. Plasma membrane, a phospholipid bilayer with proteins that separates the cell from the surrounding environment and functions as a selective barrier for the import and export of materials

3. Cytoplasm, the rest of the material of the cell within the plasma membrane, excluding the nucleoid region or nucleus, that consists of a fluid portion called the cytosol and the organelles and other particulates suspended in it

4. Ribosomes, the organelles on which protein synthesis takes place
