Detailed explanation-1: -Stomatal transpiration-This is the most dominant form of transpiration.

Detailed explanation-2: -Such type of transpiration is called as stomatal transpiration. It constitutes about 50-97% of the total transpiration. It occurs through the stomata.

Detailed explanation-3: -Stomata are the small pores on the surface of leaves that are in direct contact with the environment and carry out the process of transpiration. As the water is absorbed by the roots of the plants, it is transported to all parts through the xylem.

Detailed explanation-4: -Transpiration occurs mostly through stomata located on leaves. It also occurs through cuticle and lenticels. Foliar transpiration is the term given to transpiration that occur from the leaf surfaces, which includes the loss of water vapour through stomata and cuticles.

Detailed explanation-5: -There are three kinds of transpiration: stomatal transpiration, cuticular transpiration and lenticular transpiration. Mechanism of stomatal transpiration involves following steps: Osmotic diffusion of water from xylem to inter cellular spaces through mesophyll cells.
