Cell Membranes: The Boundaries of Life DVD

(in stock)


The fascinating world of cells is explored in this short program, first by examining cell wall structure and the major functions of cellular membranes before introducing the fluid mosaic model of the phospholipid bilayer and transport, recognition, and receptor proteins. Next are the concepts of simple and facilitated diffusion, passive and active transport, and osmosis. Endocytosis and exocytosis, the role of contractile and central vacuoles, the way desmosomes and tight junctions tie cells together, and a look at how plasmodesmata and gap junctions facilitate communication conclude the program. 31 minutes.
