2.13c osmosis in plant cells

1. Osmosis-the movement of water from dilute to concentrated solution.
2. The water moves through the cell membrane in the cell.
3. there are three conditions cinsidered for a plant cell: Hypotonic, isotinic, and hypertonic (see obj 2.13b).
4. Consequences of osmosis for plant cells- when hypotonic, the plant is described as being turgid when the volume of the cell increases.
5. When hypertonic, the cell membrane moves away from the cell wall because the volume has decreased. this creates space for the hypertonic solution to move through. This cindition a plant cell is known as plasmolysis.
6. When isotonic volume is constant because the concentration of the external solution is equal to the concentration of the internal solution.
