- Were there any differences in the amount of water in the bags from plants 1 and 3 in your transpiration experiment? If so, what could explain these differences (which variable was changed between these treatment groups)?
- What about between plants 2 and 3, considering the same questions as above?
- Plants 3 and 4?
- What did plant 3 represent in the experiment? Explain your answer.
- What is the role of water in a plant -- why do plants need it?
- Open stomata result in water loss through transpiration. Why don’t plants just close their stomata to prevent water loss?
- What environmental factors influence the amount of transpiration in plants?
- Cohesion, adhesion, tension, and capillary action act on water as it moves through the plant body. Define each of these terms and explain how they participate in the movement water through the plant.
- How does the diameter of a conducting cell in the xylem influence the ability of the plant to take up water?
