Hence, water in the form of vapor is lost through this layer. The Questions and Answers of what is translocation? Transpiration is important in plants for three major reasons: Cooling of the plant: the loss of water vapour from the plant cools down the plant when the weather is very hot. Transpiration helps keep the water balance in the plant body through the loss of water. The cuticle is a waxy covering on the surface of the leaves of the plants.

(v) … Answer: Each stomata is surrounded by guard cells. Question 6. Cuticles are waxy covering on the epidermis of the leaves. This water also evaporates and the water vapors diffuse into the sub stomal space, which finally diffuses out by stomata. Hi sir can you tell any four advantages of transpiration???? Most of the water absorbed by the roots of a plant —as much as 99.5 percent—is not used for growth or metabolism; it is excess water, and it leaves the plant through transpiration. Guttation is a similar process to transpiration in which some plants exudate the drops of xylem sap on the edges of the leaves. Cuticular transpiration occurs in plants with a thick cuticle layer and a lesser number of stomata. High temperature decreases relative humidity, which forces the stomata to open even in the dark, thus increasing the rate of transpiration. Question 1 : State the function of lenticels. - American Geological Institute, 1976. Transpiration is important because a) It helps in absorption and upward movement of water and minerals from roots to leaves. Explore more about its phenomenon @ BYJU'S. Namely, stomatal transpiration- when it occurs through the stomata. Too much of transpiration may lead to dehydration and damage to the plant. It also occurs in plants when the stomatal opening does not open under certain conditions. Name the cell that surrounds the stoma. These openings are stomata. Define transpiration. The evaporative loss of water in the form of water vapour from the aerial parts of the plants is … The relative humidity of the atmosphere is inversely proportional to the rate of transpiration.
