The Plasma Membrane & Cellular Transport


The importance of the membrane that surrounds the cell, as a regulator of the passage of materials to and from the cell, becomes apparent in this program. Captivating animations show the fluid-mosaic model in action. An impressive array of models, graphics, and accompanying narratives keep the program flowing at a lively pace.

Topics include: Structure of the Plasma Membrane; Brownian Motion; Diffusion; Concentration Gradient; Dynamic Equilibrium; Osmosis; Osmotic Pressure; Isotonic, Hypotonic, and Hypertonic Solutions; Passive Transport; and more.
