Explain : transpiration is an unavoidable event.

Text Solution

Verified by Experts

Water is continually lost from plant in the form of vapour through transpiration.
So more and more water is pulled by root.
If plant does not get water by root even though waste of water is not stopped by vapour. So physiologically leaf shrinks and plant is destroyed/dies. So transpiration is an evil in a plant.
