Detailed explanation-1: -The significance of transpiration is explained below: Transpiration helps in the conduction of water and minerals to different parts of the plants. Due to the continuous elimination of water from the plant body, there is a balance of water maintained within the plant. It maintains osmosis and keeps the cells rigid.
Detailed explanation-2: -Transportation of sugars from source to sink is a physiological process and is not related to transpiration.
Detailed explanation-3: -It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis. Transpiration results in transpiration pull which thereby increases the rate of absorption of water along with minerals from the soil through roots.
