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: -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-3: -When the stomata are open, plants lose water vapour through them as well. The water vapour evaporates from the cells lining the air spaces and then passes out of the leaf through the stomata by diffusion. This loss of water vapour is known as transpiration.

Detailed explanation-4: -In the air spaces, the water changes state and turns from a liquid into a gas called water vapor. Because there is a higher concentration of water vapor inside the leaf than outside, the water vapor moves out of the leaf through the stomata by diffusion. This process is known as evaporation.

Detailed explanation-5: -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.
