- Effects of Water Potential on Generic Cells
- Immersed in concentrated salt/sugar solution
- Hypertonic solution
- Water moves out of cells by osmosis, down its potential gradient
- Animal cells shrink and shrivel up
- Plant cell vacuoles shrink, pulling the plasma membrane away from the cellulose wall. Plasmolysis has occurred.
- Immersed in distilled water
- Hypotonic sloution
- Animal cells swell before bursting as their membranes cannot withstand the pressure. Cytolysis has occured.
- Plant cells become turgid but their cellulose cell walls prevent them from bursting
- Water moves into cells by osmosis, down its potential gradient
- Immersed in solution with same water potential
- Isotonic solution
- Cells therefore remain the same shape and volume
- Immersed in concentrated salt/sugar solution
