1 Diffusion and Osmosis

2 Diffusion and Osmosis The exchange of materials in and out of a cell
This occurs through the cell membrane

3 Diffusion Movement of particles from an area of high concentration to an area of low concentration Particles want to move from very crowded areas to less crowded areas Example – spraying air freshener in a room

5 Osmosis The diffusion of water through a cell membrane pure water
dilute solution concentrated solution

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.

Movement of Materials Through The Cell Membrane For a cell to maintain its internal environment, (i.e., achieve homeostasis) it has to be selective in.
