Dixon- Joly theory is also known as Cohesion-Tension theory Water escapes from specialized structures called hydathodes. In tall trees transpiration pull can draw water up to 50 meter height. This transpiration creates a suction – a pull which makes the water flow upward from roots. Participate in learning and knowledge sharing. This rush of water towards the vacuum creates a mechanical force that enables to pull up water absorbed by the roots through the stems. Thus, the weight of the entire set will decrease. The process of release of water in the form of water vapor is called transpiration. This force helps in the movement of water as well as the minerals dissolved in … Transpiration pull or the suction force is the force which aids in drawing the water upward from roots to leaves. Available for CBSE, ICSE and State Board syllabus. Question 6 What is translocation? Bark is thick with outermost layer, (f) In both perspiration and transpiration, water is lost by evaporation from the body of the, (g) On a bright sunny day, the rate of transpiration is much higher than any other days. ICSE Solutions for Chapter 4 Transpiration Class 10 Biology. So no water is lost from the leaf through transpiration since the stomatal openings get blocked by vaseline. 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. 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. Transpiration is the evaporation of water from plants. It is the removal of water from the plant because of injury. Expert Answer: Water is transpired from the plants leaves via the stomata.
