Movement of
Substances
- Osmosis
- Net movement of water
molecules
- Higher water potential > Lower water potential
- Water potential tendency of movement
- Plant cells
- H2O outside < H20 in cell
- Plasmolysed
- H2O outside > H20 in cell
- Turgid
- Animal cells
- H2O outside > H20 in cell
- Cytolysis
- H2O outside < H20 in cell
- Crenated
- Diffusion
- Net movement of particles
- Higher region of concentration > Lower region of concentration
- Down a concentration gradient
- Steeper gradient = Faster rate
- Occurs until evenly distributed throughout region
- Biological systems
