Question

Does transpiration serve any useful function in the plants? Explain?

Answer 1

Transpiration is the process of loss of water from the aerial parts of the plants such as stems, leaves, and flowers. About 97-99.5% of water is lost through the process of guttation and transpiration. Transpiration is of three kinds: Stomatal transpiration, Cuticular transpiration, and Lenticular transpiration. Transpiration that takes place by a young or mature stem is known as Cauline transpiration. Transpiration carries minerals and water to the leaves for photosynthesis.

Complete answer:
-Yes, transpiration is very much a necessary process in plants.
-Transpiration is the process by which water gets evaporated from the plants.
-Transpiration occurs through stomata. Stomata are present on the leaf surface.
-Transpiration helps plants to pass water from roots to upper parts of plants thereby distribute water to all plant parts.
-Transpiration also maintains the cooling of the plants.
-Cooling is necessary for plants for many reasons.
-Transpiration helps in the exchange of gases.

Additional information:
-Stomatal transpiration is the diffusion of water vapours by stomata.
-Lenticular transpiration is the evaporation of water through lenticels.
-Cuticular transpiration is the loss of water directly through the external membranes.
-Stomatal transpiration is the most common kind of transpiration.

Note: Transpiration is the flow of water through a plant and its loss from aerial parts of the plant such as stem, leaves, and flowers. This process provides cooling to the plant, enables the movement of water and mineral nutrients from roots to shoots. Transpiration changes the osmotic pressure of cells. It maintains the moisture conditions in the atmosphere. The rate of transpiration is affected by humidity, light intensity, temperature, and wind speed.
