NEET BIOLOGY

Detailed explanation-1: -The process of transpiration keeps the cell turgid, cools the surface of the leaves, and helps in the movement of minerals from the soil to different parts of the plant.

Detailed explanation-2: -Transpiration is loss of water in the form of vapour through aerial parts of the plant. This creates a suction force that pulls water along with minerals from the roots to the leaf. When water evaporates through the plant, it absorbs heat, which in turn cools down the plant.

Detailed explanation-3: -Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is ‘pulled’ into the leaves.

Detailed explanation-4: -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-5: -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.
