Question

Does transpiration occur at night?

Answer 1

Transpiration:

1. Water is lost from the aerial regions of plants in the form of water vapor through a biological process, it is called transpiration.
2. Since stomata are closed at night, it is generally believed that transpiration only happens during the day.
3. Stomata, however, can be open at night and closed during the day in some succulent plants.
4. But the rate of transpiration is lower at night.
