Detailed explanation-1: -Plants release excess water from their body through stomata and some other parts. The water is released in the form of vapour. This process is called as transpiration.

Detailed explanation-2: -Transpiration. Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapour and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves.

Detailed explanation-3: -Transpiration is the evaporation of water in the form of water vapour from plants. It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis.

Detailed explanation-4: -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-5: -Transpiration is the loss of water through stomata, so, more stomata are found on the lower surface to prevent excessive loss of water. As the lower surface of leaf is not directly exposed to sun, rate is transpiration is low from the lower surface. Q.
