| Across what membrane does osmosis occur? | Partially permeable |
| What is the water potential of pure water? | 0 |
| Define water potential | The tendency for water to leave a solution |
| What happens to the water potential when a solute is added to a solution? | The water potential decreases |
| Are values of water potential always positive or negative? | Negative |
| What is an isotonic solution? | When the two solutions have the same concentration |
| What happens to a cell in a isotonic solution? | Nothing |
| What is a hypotonic solution? | Where the concentration of the solution is less than that of the cell in it |
| What is a hypertonic solution? | A hypertonic solution has a greater concentration of solutes than the cell in it |
