Cell Biology: The Plasma Membrane
- 1988 ----- color ----- 14 min ----- vhs
- The essential function of the cell membrane is not only to contain and protect, but to act as a gateway for molecular traffic. The processes of diffusion, osmosis, active transport, and endocytosis are shown as the primary means of transferring molecules to and from cells through the membrane, providing needed chemical reactions, maintaining a stable interior environment, and allowing a way for electronic signals to be passed to other cells--all of which are necessary for sustaining life.
- Topics: (Biology, Microbiology)
