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. During the process of transpiration, water molecules in the plant tissues are removed from the aerial parts of the plants.
Detailed explanation-2: -Plants breathe through their stomata, little openings that allow transpiration, which is the outward passage of water vapor along with carbon dioxide. This vapor then evaporates into the air as part of the process of photosynthesis.
Detailed explanation-3: -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.
