Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. What is water potential?
The potential energy of water per unit volume relative to pure water in reference conditions.
The amount of water present in a solution.
The rate at which water moves across a membrane.
The pressure exerted by water on a cell wall.
2. Which component contributes to the solute potential (Ψs) of a solution?
Temperature
Presence of dissolved solutes
Atmospheric pressure
Light intensity
3. Water moves from an area of water potential to an area of water potential.
4. The pressure exerted by the cell wall on the protoplast is called pressure.
5. Pure water has the highest possible water potential, which is zero.
True
False
6. A plant cell placed in a hypotonic solution will undergo plasmolysis.
True
False
7. Explain the relationship between water potential, solute potential, and pressure potential.
8. Describe what happens to a plant cell when it is placed in an isotonic solution. Use the diagram below to aid your explanation.
