Detailed explanation-1: -This process of elimination of excess water from the plant body is known as transpiration. It is generally the evaporation of water from the surface of the leaves.

Detailed explanation-2: -Excretion is carried out in the plants in the following ways: The gaseous wastes, oxygen, carbon dioxide, and water vapor are removed through the stomata of leaves and lenticels of stems. Some waste products collect in the leaves and bark of trees. When the leaves and bark are shed, the wastes are eliminated.

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: -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-5: -The process by which water vapor leaves the stomata is evaporation.
