Detailed explanation-1: -Transpiration : excess water taken up by the plants is released into the air in the form of water vapour through stomata. The process is called transpiration. It keeps the plant cool.
Detailed explanation-2: -Leaves absorb carbon dioxide from the air, combine it with water that comes through the roots of the plants to make food (a sugar molecule known as glucose), and release oxygen into the air.
Detailed explanation-3: -The main functions of leaves are photosynthesis, exchange of gasses and transpiration.
Detailed explanation-4: -Oxygen and water vapor exit the leaves through stomata, as well. In many plants, when the outside temperature is warm and water evaporates more readily, plants close their stomata to prevent excessive water loss.
