Diffusion
- passive movement of particles from an area of high concentration to an area of low concentration
- the greater the difference in concentration, the faster the rate of diffusion
- example: oxygen required for respiration diffuses into cells and carbon dioxide produced by respiration diffuses out of cells
Osmosis
- the diffusion of water molecules from a dilute solution to a more concentrated solution through a partially permeable membrane
- (from an area where there's…
