Detailed explanation-1: -The water eventually is released to the atmosphere as vapor via the plant’s stomata-tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.
Detailed explanation-2: -Transpiration is the evaporation of water from plants occurring at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis.
Detailed explanation-3: -Our results corroborate earlier predictions that most evaporation occurs from the epidermis at low light and moderate humidity but that the mesophyll contributes substantially when the leaf center is warmed by light absorption, and more so under high humidity.
