Detailed explanation-1: -the stomata in leaves. the cuticle in the leaves and young stem. the lenticels in old stem.

Detailed explanation-2: -2.3. 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-3: -Transpiration is a process by which plants lose water to the atmosphere in the form of water vapour. This is carried out by the small pores present on the underside of the leaves.

Detailed explanation-4: -Transpiration is defined as the physiological loss of water in the form of water vapor, mainly from the stomata in leaves, but also through evaporation from the surfaces of leaves, flowers, and stems.

Detailed explanation-5: -Transpiration occurs through stomata. Stomata are usually open during the day and close at night. When the stomata opens, the water near the surface of the leaves turns into vapour and evaporates. Stomata in succulents or CAM plants stay closed throughout the day and open only at night.
