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

Detailed explanation-2: -Leaf stomata are the primary sites of transpiration and consist of two guard cells that form a small pore on the surfaces of leaves. The guard cells control the opening and closing of the stomata in response to various environmental stimuli and can regulate the rate of transpiration to reduce water loss.

Detailed explanation-3: -Stomata are small openings in a leaf which help in loss of excess water (transpiration) and also diffusion of gases. Specialised cells known as guard cells surround stomata and their function is to open and close stomatal pore.

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.
