| Does a concentrated sugar solution have a high or low water potential? | Lower |
| What happens to a cell placed in a concentrated sugar solution (in terms of movement of water)? | Water moves from an area of higher water potential inside the cell to an an area of lower water potential outside the cell (water moves out the cell) |
| What happens as a result of animal cells losing water? | The cell volume decreases The inside of the cells concentration increases |
| What happens as a result of the cells contents concentration increasing? | Metabollic reactions effected |
| What happens to a cell placed in a solution with higher water potential (in terms of movement of water)? | Water moves from an area of higher water potential outside the cell to an area of lower water potential inside the cell (water moves into the cell) |
| What happens as a result of water moving into an animal cell? | Pressure inside the cell increases Lysis |
| What is crenation? Does it happen to animal or plant cells? | When an animal cell shrivels |
| What is lysis? Does it happen to animal or plant cells? | When animal cells burst |
| Why do animal cells burst and plant cells dont? | Plant cells have a cell wall to prevent bursting and the animals fragile plamsa membrane can't handle the higher pressure in the animal cells |
| What happens to plant cells when they lose water? | Cell volume decreases Plasmolysis |
| What is plasmolysis? | When the cytoplasm and plasma membrane pull away from the cell wall |
| What happens to a plant cell when water moves into the cell? | The cell volume increases Cell contents push on the cell wall Cell becomes tirgid |
| What's happened to the cell when it becomes tirgid? | The cell swells |
