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: -Transpiration is the evaporation of water from plants occurring at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis.
Detailed explanation-3: -Transpiration is defined as the physiological loss of water in the form of water vapor. It also evaporates from the surfaces of leaves, flowers, and stems. Transpiration has two main functions namely, cooling the plant and pumping water and minerals to the leaves for photosynthesis.
Detailed explanation-4: -Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves.
Detailed explanation-5: -Transpiration is defined as the physiological loss of water in the form of water vapor, mainly from the stomata in leaves, but also through evaporation from the surfaces of leaves, flowers, and stems.
