Transport

Transport. Plasma membrane/cell membrane. How does it control what goes into and out of the cell????. Permeable:. Can pass through. Allows only certain molecules to pass through. Selectively permeable:. BUT. Not all molecules get in the same way!. Selective Permeability.

Cellular Transport

Cellular Transport. Unit 5. Passive Transport. Does not use energy 1. Diffusion Movement of particles from an area of higher concentration to an area of lower concentration. Dynamic Equilibrium - Tries to reach an equal concentration inside and outside the membrane

Osmosis

Osmosis. Osmosis is the net movement of water molecules over a partially permeable membrane from an area of less osmotic potential to an area of more negative osmotic potential. . Water potential.
