Transpiration plays a key role in the production of foods and different chemicals by malting a continuous supply of water to leaves. This exothermic process uses energy to break the strong hydrogen bonds between liquid water molecules; the energy used to do so is taken from the leaf and given to the water molecules that have converted to highly energetic gas molecules. In the water cycle, it plays a major role as approximately 10% of total water which is present in the atmosphere is because of the transpiration process. It is thought that transpiration enhances nutrient uptake into plants. It helps in the exchange of gases and provides coolness to the plant body. 4.Why is it important to calculate the surface area of the leaf? Water deficit decreases growth and hence the plant gives a stunted appearance. This exothermic process uses energy to break the strong hydrogen bonds between liquid water molecules; the energy used to do so is taken from the leaf and given to the water molecules that have converted to highly energetic gas molecules. What is fertilization? Transpiration is helpful to plants in many ways. Although the plant cannot afford to lose too much water to the environment, the plant must have a way to carry water and minerals from the roots, up the stem, and out to the leaves. It helps in the development of the plant body by absorption and distribution of water in plants. An osmotic balance of the cell is maintained by the procedure of transpiration. Evaporative cooling: As water evaporates or converts from a liquid to a gas at the leaf cell and atmosphere interface, energy is released. Opening and closing the stomata is possibly the plant's most important means of regulating water loss via transpiration. It helps in sending out extremely absorbed water by plants and transport of mineral salts in plants. Accessing nutrients from the soil: The water that enters the root contains dissolved nutrients vital to plant growth. Answer (1 of 3): Transpiration is what happens when a plant obtains the carbon dioxide gas it needs from the air for photosynthesis. Importance of transpiration for the plant Decrease of plant temperature. Liquid water extends through the plant from the soil water to the leaf surface where it is converted from a liquid into a gas through the process of evaporation. 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. Helps in receiving water and inorganic salts. In the process, water from the plant tissues is lost to the atmosphere. In extreme heat, plants are severely stressed and can die. Moves minerals up from the root (in the xylem) and sugars (products of photosynthesis) throughout the plant (in the phloem). 2. It is the evaporation of water from plants, especially from the leaves, but also from the stems. Open stomata allow water vapor to leave the leaf but also allow carbon dioxide (CO2) to enter. Transpiration happens during the day at high temperatures and occurs when moisture or water leaves the plant in the form of a vapor. Transpiration produces a tension or ‘pull’ on the water in the xylem vessels by the leaves. Transpiration - Factors Affecting Rates of Transpiration. Transpiration - What Controls Rates of Transpiration? Plants with greater water use efficiencies are better able to withstand periods when water in the soil is low. A lack of transpiration (evaporation) is a common cause of Blossom End Rot – interruption to the calcium supply. Transpiration compels the plants to absorb plenty of unnecessary water. Wilting reduces photosynthesis and other metabolic activities. Why do plants transpire? Due to transpiration certain hydrophilic salts may be stored on the leaf surface which keeps the loaf moist and sometimes reset the fungal infection. what is transpiration and why is it important? Excess cutting of trees has resulted in the imbalance in the nature’s cycle and has caused … Transpiration is the evaporation of water from plants. It helps in the exchange of gases and provides coolness to the plant body. (c) It helps a plant to get rid of excess water.
