In hypotonic solutions (higher WP), animal cells lyse, while plant cells develop turgor pressure; in hypertonic solutions (lower WP), animal cells crenate, and plant cells plasmolysis.

| Front | Osmosis in animals/plants 2.1.5(e) |
|---|---|
| Back | Solution has higher WP - animals, water moves in by osmosis, higher HP, cell membrane can’t withstand so bursts (cytolysis or cell lysis) - plants, water moves in by osmosis, higher HP pushes membrane against cell wall (turgor pressure) Solution has lower WP - animals, water moves out by osmosis, lower HP, cell crenation - plants, water moves out by osmosis, lower HP which pulls cell membrane away from cell wall (cell plasmolysed) |
