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 necessary to sustain life. Produced by Bill Walker Productions in association with BioMedia Associates. A Coronet release.
