PPT-Diffusion and Osmosis: How does stuff get into and out of a

The Cell in its Environment Ch 7 Section 2 L3 Biology Molecules are always moving Molecules move randomly and bump into each other and other barriers Diffusion Movement of molecules from an area of high concentration to an area of lower concentration . Diffusion. : The passive movement of particles from a region of high concentration to a region of low concentration until equilibrium is reached. (Molecules still move after equilibrium is reached) . Have you taken the latest quiz?. When is your next paper due?. If you are not sure, you need to. Plasma Membrane: the bouncer. (controls who gets in and who leaves). The plasma membrane. phospholipid bilayer. Cell membrane compared to a sieve/colander.. When would you use a colander?. What does a cell membrane and a colander have in common?. All cells are surrounded by a cell membrane. Cell membranes . keep things out and keep things in..
