Explanation:
Detailed explanation-1: -In plants, maximum transpiration takes place through stomata present on the leaves and it amounts to 80-90% of total transpiration.
Detailed explanation-2: -Transpiration occurs through the stomatal apertures, and can be thought of as a necessary “cost” associated with the opening of the stomata to allow the diffusion of carbon dioxide gas from the air for photosynthesis.
Detailed explanation-3: -Transpiration mainly takes place in the aerial part of the plant, stomata of leaves evaporate high amounts of water in form of vapour which helps to keep the plant cool.
