Answer: A pulling force called suction, caused by the evaporation of water in a leaf draws a long, continuous column of water through the xylem from the root to the leaf. Water is absorbed from the soil by the roots and there is an upward movement of water through the stem of the plants. (c) The structure of stoma remains same in monocots as well as in dicots. The upward movement of water against the gravitational pull is caused by the transpiration pull. Transpiration pull is also referred as suction force and this force is used to draw the water in an upward direction from the roots to the leaves. Explain the transpiration pull theory. Class 10 Biology ... because of this attraction they pull on the molecules behind and as a result these start moving away and then they start pulling on the ones behind them and they start moving on the ones behind them. The remaining 97–99.5% is lost by transpiration and guttation. Water molecules stick to one another through cohesion forming a column in the xylem. When water evaporates through the leaves, a pull is created through the xylem, and water moves back to the leaves. Answer: Water in the mesophyll cells of leaves (cells located below the stomata) is in contact with water or sap in xylem of leaf petiole, stem and root. The amount of water received by the leaves are used for the photosynthesis and the excess amount of water is released into the atmosphere in the form of vapours through the openings in the leaves known as stomata. Transpiration pull or the suction force is the force which aids in drawing the water upward from roots to leaves. Since, transpiration is also an upward movement of water, the phenomenon further increases or facilitates the transportation of water through the stem. The value of Q 10 for transpiration is 2.

The transpiration pull is just one of the mechanisms that explain the movement or translocation of water in plants, particularly water ascent in tall trees. Question 9. More the, (e) Cork and Bark of trees are tissues of old woody stems. Transpiration would occur faster. Transpiration. This water evaporates by … Transpiration is the loss of water in the form of vapours from the aerial spaces in the leaves. Transpiration pull or the suction force is the force which aids in drawing the water upward from roots to leaves. The movement of water out of the leaf stomata creates, when the leaves are considered collectively, a transpiration pull. Hence, the stoma from the diagram can be of a monocot leaf or of a dicot leaf. Participate in learning and knowledge sharing. Sample papers, board papers and exam tips. (c) Yes, the transpiration rate will increase. Question 1 Name the two conducting tissues of plants? It is the removal of water from the plant because of injury. The process of release of water in the form of water vapor is called transpiration. It is carried there via leaf veins and vascular bundles within the plants cambium layer. Could you please explain me what is cell to cell osmosis and how does it occur. In tall trees transpiration pull can draw water up to 50 meter height. Transpiration Pull. Frank ICSE Class 10 Biology Solutions – Transpiration PAGE NO:60 Solution 1: Transpiration: It is the loss of water in the form of water vapour from aerial parts of the plant. Thus the transpiration pull acts as pull from above on the-whole of water column of the plant which pushes the water column of xylem vessels of roots lowers leaves i.e. 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. In leaves, some amount of water is used for photosynthesis and excess water is released into atmosphere through openings called as stomata. Transpiration refers to the movement of water vapor from the leaves to the atmosphere through the stoma whereas translocation refers to the movement of nutrients produced by the leaves throughout the plant body. The whole process can be compared with a person (transpiration pull) pulling a bucket full of water (forces on water column) from a well with a rope (column of water due to cohesion). Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.Transpiration is essentially evaporation of water from plant leaves.. Transpiration pull is the force which aids in drawing the water upward from roots to leaves. The. 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.
