Detailed explanation-1: -Transpiration provides a suction force that is required for the absorption of water, which is required for photosynthesis. As molecules line up for absorption in the xylem tissues, the first molecule is lost by the plant owing to transpiration.

Detailed explanation-2: -Transpiration results in transpiration pull which thereby increases the rate of absorption of water along with minerals from the soil through roots. Transpiration helps in transportation of absorbed minerals to all the parts of the plant. Transpiration provides water for the process of photosynthesis.

Detailed explanation-3: -As a result of transpiration, a suction force is created in the xylem vessel. This force causes water to be pulled up from the xylem in the roots to the stem and leaves. This pulling force is called transpirational pull.

Detailed explanation-4: -Xylem is the tissue which transports water and minerals in plants.

Detailed explanation-5: -Cools the surface of the leaves. Helps in growth and development. It controls the temperature of the plants. Allows the movement of minerals from the soil to different parts of the plant.
