Effect of osmotic pressure on cells correct answers The changes in diffusion gradient of water -Higher osmotic pressure, more stress on cell Cells are 80-90% H2O Cell walls resist hypotonic solutions, but few organisms can resist hypertonic solutions Isotonic Solution: No net movement of water particles. Cell membrane is attached to cell wall. Hypertonic Solution: Water particles move out of the cell. Cell membrane shrinks and detaches from cell wall (plasmolysis) Hypotonic ...
