Explanation:
Detailed explanation-1: -Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is ‘pulled’ into the leaves.
Detailed explanation-2: -So, The loss of water through the stomata of leaves is called transpiration.
Detailed explanation-3: -Water is transient in plants. Less than 1 per cent of the water reaching the leaves is used in photosynthesis and plant growth. Most of it is lost through the stomata in the leaves. This water loss in vapour form is known as transpiration.
