Explanation:
Detailed explanation-1: -But when limited water is available in the soil, plants try to prevent water loss. Water loss through transpiration can be reduced by closing the stomata in the leaves using a substance called ABA.
Detailed explanation-2: -Transpiration is closely related to stomata. Nearly 97 % of water from plants is lost through stomatal transpiration, so the more stomata, the higher the transpiration rate [3].
