Description

This program looks at the structure of cell membranes and their function, including compartmentalisation, regulation of the movement of materials, access to information, intercellular interaction, and as a location for biochemical activities. Using a combination of narration, video footage and graphics, the program covers how cell membranes operate and various ways in which materials can cross them, including diffusion, active and passive transport, osmosis, endo- and exocytosis. It also looks at some of the effects of osmosis, including plasmolysis and turgor in plants. Finally the program studies why the surface area to volume ratio of living things is important, and how organisms overcome the tendency for this ratio to decrease, as they grow larger.
