Detailed explanation-1: -Transpiration is the loss of water in the form of vapour through aerial parts of the plant. This creates a suctional force pulling water from the roots through the xylem. Transpiration helps to pull water to the leaves of tall trees that are even 600ft high.
Detailed explanation-2: -Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
Detailed explanation-3: -Transpiration helps in maintaining the concentration of the sap inside the plant body: The roots continue to absorb water from the soil. If excess water is not evaporated out, the sap would then become dilute, preventing further absorption of water and minerals.
