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: -Significance of transpiration:-Transpiration is generally helpful for the conduction of water and nutrients in the plants.-Transpiration helps to maintain the water balance, as there is absorption and elimination.-Transpiration helps the cells to maintain osmosis, so the cells are rigid.

Detailed explanation-3: -Transpiration : The evaporation of excess water from the stomata present in leaves of plants is called transpiration. Two functions : i It is important for upward movement of water in plants. ii It helps in regulating temperature of plant.

Detailed explanation-4: -Transpiration is the evaporation of excess water from the surface of a leaf, through the stomata. Transpiration produces a cooling effect and thus saves the plant from the hot sun.

Detailed explanation-5: -Solution : Transpiration does not help in translocation of sugars from source to sink.
