this is a paper 2, separate science fact.
- When water diffuses into cells, it makes the plant cells turgid
- This provides the plant with support because it can stand upright
- If the water diffuses out of the cell, it becomes flaccid and wilts
- The cell is turgid because the water entering the cell makes the cytoplasm and the vacuole push against the cell wall. This creates turgor pressure and effectively forces the plant to stand upright
