Question

To compare the rate of transpiration in different plant species

Answer 1

Explanation:

Most of the water entering a plant's root will exit the leaves by transpiration. Transpiration in plants is the passage of watery vapor through the stomata of plant tissue.

By knowing the amount of water exiting each plant trough the process of transpiration we can estimate the amount of water the plant needs. We can also compare different plants based on their need to water and select the best plants for different locations based on the availability of water.

The rate of transpiration may also change in different hours of the day, so while using automated irrigation systems, we can increase or decrease the amount of water supplied to the plant based on the time of the day.
