Sorry!, This page is not available for now to bookmark. This thin water layer then evaporates. The remaining water is released by the plants into air as water vapour through the small pores in their leaves (called stomata). Thus, transpiration can be defined as the process by which the plant body releases water in the form of vapors through its aerial parts. Plants are no different, they also have to get rid of the excess water from their body. VERY SHORT ANSWER TYPE ICSE Class 10 Transpiration. Transpiration helps keep the water balance in the plant body through the loss of water. 1. Also, the cell sap of cells in leaves exert pressure on the outward of the cell wall. This results in the closing of the stomata and even wilting. Define the above mentioned process. Hence stomata are provided with guard cells that regulate the entire process. It causes around 20% of transpiration in plants. 2. BOOK FREE CLASS The loss of excess water by diffusion through the stomata of leaves of a plant into the atmosphere is called transpiration. It gets rid of the excess water absorbed by roots and returns it back to the atmosphere. Answer : Lenticels help in facilitating the process of transpiration in woody plants. Hence, water in the form of vapor is lost through this layer. 2. Lenticels are a porous tissue found on the barks of woody stems and roots of dicots. B. ; Stomata help in exchange of gases, which is intake of carbon dioxide and release of oxygen in the presence of water and sunlight by the process of photosynthesis. 0 votes . Relative humidity means the amount of water vapor present in the atmosphere expressed as a percentage of the number of water vapors needed for saturation at that same temperature. Define the phenomenon. Question 1. ; The transpirational pull: when the plant loses water through transpiration from the leaves, water and mineral salts from the stem and roots moves, or is `pulled', upwards into the leaves.Water and is therefore taken up from the soil by osmosis … Thus, decreasing the transpiration rate.

During scarcity of water, roots absorb less water from the soil. About 5-10% of the water from the leaves is lost through cuticular transpiration. This loss of water in the leaves exerts a pull on the water in the xylem ducts and draws more water into the leaf. When transpiration takes place through leaves, it is foliar transpiration. When water enters the guard cells, they swell and open and when the water leaves the stomata they relax and close. Transpiration Questions and Answers ICSE Class 10. List any three major factors that accelerate the rate of transpiration. Two types of forces, cohesive and adhesive force work together to bring about this upward pull. The cuticle is a waxy covering on the surface of the leaves of the plants. Transpiration rate is affected by a series of environmental and other morphological factors. Stomatal transpiration accounts for 85%- 90% of the total water loss in plants. Cuticular transpiration takes place through the cuticle (waxy layer) covering the leaves. In Stomatal transpiration, water in the surface of the leaves is evaporated into the atmosphere when the stomatal opening opens. Various environmental factors, such as the presence of light, relative humidity, temperature, wind speed, availability of water, and cellular factors like the orientation of leaves, number of stomata, cuticles, and lenticels affect transpiration.
