Cuticular transpiration takes place through the cuticle (waxy layer) covering the leaves. Structured/Application/Skill type | Q 6.3 | Page 67. 1 answer. In such atmospheric conditions, water vapors accumulate around the transpiring organs and reduce the rate of diffusion. B. Plants leaves have microscopic openings on the epidermis which are meant for gaseous exchange and transpiration. The surface of mesophyll cells in leaves release a thin layer of water. Stomatal transpiration is one form of foliar transpiration. Does Increased potassium ion concentration in the guard cells, make the guard cells a hypertonic or hypotonic solution? As the name suggests the type of transpiration that takes place through cuticles is cuticular transpiration. 2. The amount of water lost by plants over a period of time refers to the rate of transpiration. Transpiration also refers to the evaporation of water from the plant part. When water enters the guard cells, they swell and open and when the water leaves the stomata they relax and close.

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. Transpiration is the process by which excess water in plants is lost to the atmosphere in the form of water vapour through tiny pores present on the surface of the leaf called stomata. Cuticular transpiration occurs in plants with a thick cuticle layer and a lesser number of stomata. VI. ; Plants prepare their food by photosynthesis. It also occurs in plants when the stomatal opening does not open under certain conditions. The upward movement of water against the gravitational pull is caused by the transpiration pull. Transpiration is the evaporation of water from plants. Watch concept videos to understand the significance of stomatal transpiration. Plants are no different, they also have to get rid of the excess water from their body. Still, air lowers the rate of transpiration.

Trophic … Cuticular transpiration accounts for around 5%- 10% of the total water loss. Roots in plants absorb water from the ground which is transported to all the plant parts for various activities like preparing food, growth, and metabolism. Criteria of life- (i) Growth (ii) Movement Nutrition-The process in which an organism takes in food, utilizes it to get energy, for growth, repair and maintenance, etc. Transpiration is the loss of water in the form of vapor through pores present in the plant body. Guttation is a similar process to transpiration in which some plants exudate the drops of xylem sap on the edges of the leaves. It promotes the proper growth of plants and cell division. For good health and cellular growth, the water needs to be excreted out. About 5-10% of the water from the leaves is lost through cuticular transpiration. Like all other life processes (eating, digestion, growth, etc.) During dry conditions when the stomata are closed, more water is transpired through the cuticles. This water also evaporates and the water vapors diffuse into the sub stomal space, which finally diffuses out by stomata.
