For cell division turgidity of the cell are required. Firstly evapotranspiration and the loss of water through the leaves allows the plant to uptake more water from the roots and therefore uptake more nutrients. It helps in maintaining the level of CO2 and O2. A suction force is created due to transpiration. In the process, water from the plant tissues is lost to the atmosphere. A look into the photosynthesis process would help to understand this fact more clearly. Transpiration is an evaporative cooling system that brings down the temperature of plants, but since it leads to water loss, it must be accurately regulated. It provides the water needed for food manufactured by photosynthesis in the leaves. (b) Ascent of sap is necessary to make water available for photosynthesis. It helps in the absorption of carbondioxide (CO J from the atmosphere during photosynthesis as the openings of stomata in … Accessing nutrients from the soil: The water that enters the root contains dissolved nutrients vital to plant growth. Best answer Transpiration is important for plants because (a) it helps in absorption and upward movement of water and minerals from roots to leaves (b) it prevents the plant parts from heating up. This process has been termed the Cohesion Theory of Sap Ascent in plants. A lack of transpiration (evaporation) is a common cause of Blossom End Rot – interruption to the calcium supply. It creates a negative pressure gradient that helps draw water and minerals up through the plant from its roots. This benefits both plants and humans. If moisture is unable to evaporate from leaves, a plant cannot absorb moisture and nutrients through its roots. The water transported upwards from the roots to the leaves also contains dissolved mineral salts which are used to produce a diversity of materials such as proteins in the plant. Evaporative cooling: As water evaporates or converts from a liquid to a gas at the leaf cell and atmosphere interface, energy is released. All rights reserved. The stomata on the underside of the leaf regulate transpiration. The leaf surface area helps to estimate the number of stomata, which could speed up or slow the rate of transpiration. Transpiration is the process in which plant roots absorb water and then release the water in the form of vapour through the leaves. First of all, transpiration drives the "circulatory" system of the plant. It helps in the absorption of carbon dioxide from the atmosphere throughout photosynthesis as the openings of stomata in day time help gaseous exchange. Two major factors influence the rate of water flow from the soil to the roots: the hydraulic conductivity of the soil and the … Carbon dioxide is needed for photosynthesis to operate. Transpiration is helpful to plants in many ways. Transpiration produces a tension or ‘pull’ on the water in the xylem vessels by the leaves. This causes the plant cells to cool down and prevents straight daylight from the damage the fragile cells. Water preserves the turgor pressure in cells much like air inflates a balloon, giving the non-woody plant parts form. a) Transpiration plays an important role in the upward translocation of water and mineral salts. Reduced Growth: Transpiration reduces availability of water inside the plant. Transpiration forever happens alongside gravity.
