Detailed explanation-1: -Evapotranspiration also includes transpiration, which is the water movement from the soil to the atmosphere via plants. Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves.
Detailed explanation-2: -Reason: Transpiration is the process of water movement through a plant and its evaporation from aerial parts.
Detailed explanation-3: -Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is ‘pulled’ into the leaves.
Detailed explanation-4: -Transpiration is the process by which plants lose water through small pores called stomata present on the underside of the leaves. The main functions of transpiration in plants are cooling and the absorption and conduction of water from roots to other parts of the plant.
Detailed explanation-5: -Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.
