Osmosis Review

1. Hypertonic solutions Plant cells the central vacuole loses water and the cells shrink causing wilting. Animal cells shrink (plasmolysis)
3
2. Hypotonic Solution Plant cells CV fills with water, plant becomes stiff and rigid, CW keeps the plant from bursting Animal cells swell, may burst (“LYSIS”)
4
3. Isotonic solutions Plant cells Equilibrium Animal cells - water moves back and forth – no change – GOOD!!!
5
PredictPredict what would happen to the cells below…. 1. RBC – hypotonic solution 2. Elodea – isotonic solution 3. Paramecium – hypertonic solution
