- Osmosis in Plants
- Rely on osmosis to support stems and leaves.
- When the water moves into plant cells, the vacuole swells
- It pushes cytoplasm against the plant cell walls, pressure builds up till no more water can enter cell
- This makes the plant cell turgid
- ? must be higher conc of water OUTSIDE cell
- If not then water moves out the vacuole and the cell shrinks, collapses and becomes flaccid.

- Osmosis in Animals
- If water in cells is used up/produced by chemical reaction, then osmosis brings water in/out. This keeps balance in the cells
- If solution outside cell is more dilute, water moves into the cell, which causes it to become turgid and it may burst.
- The cell can no longer survive
- If solution inside cell is more dilute, then water moves out of cell. The cytoplasm will be too concentrated and the cell will shrivel and become crenated.
