1. Describe the process of transpiration in vascular plants. 2. Describe any experimental controls used in the Investigation. 3. What environmental factors that you tested increased the rate of transpiration? Was the rate of transpiration increased for all plants tested? 4. Did any of the environmental factors (heat, light, or wind) increase the transpiration rate more than the others? Why? 5. Which species of plants that you tested had the highest transpiration rates? Why do you think different species of plants transpire at different rates? 6. Suppose you coated the leaves of a plant with petroleum jelly. How would the plant's rate of transpiration be affected? 7. Of what value to a plant is the ability to lose water through transpiration?

Step 1
Transpiration is the process by which water is lost from a plant through the evaporation of water vapor from its leaves, stems, and flowers. In vascular plants, this process occurs mainly through the stomata, which are small openings on the surface of leaves. Show more…

What environmental factors increase the rate of transpiration in vascular plants? Do any of the environmental factors (heat, light, or wind) increase the transpiration rate more than the others? Why? Why do you think different species of plants transpire at different rates? Suppose you coated the leaves of a plant with petroleum jelly. How would the plant's rate of transpiration be affected? Of what value to a plant is the ability to lose water through transpiration?

Transpiration is an important mechanism in plants for maintaining water balance. A transpiration experiment was conducted using two plant species and the collected data is shown below. Using the information provided, calculate the rate of transpiration of both species at 5 and 15 minutes. Describe how the structure of water allows for the process of transpiration to occur.

1. How would the rate of transpiration differ between an arid environment compared to a humid one? Why? 2. What would you expect to happen to a plant when the rate of transpiration exceeds the rate of water uptake? Why?
