Description: This film is a study of diffusion as it takes place in living cells. Photomicrography, time-lapse photography, simple lab demonstrations, and a dynamic model all help to explain diffusion, clarify how a selectively permeable membrane functions, and demonstrate the effects of osmosis (diffusion of water) on plant cells., Utilizes demonstrations and animation to explain the concepts of diffusion and osmosis. Employs an apparatus consisting of a large number of beads on a vibrating table to illustrate several aspects of both concepts. Includes the sugar-water thistle-tube demonstration.
