It creates a negative pressure gradient that helps draw water and minerals up through the plant from its roots. Transpiration is a term used for the release and evaporation of water from all plants including trees. The importance of transpiration in plants is to cool the plant and provide water and nutrients to the leaves. Plants waste much of their energy in absorbing large quantities of water and most of which is ultimately lost through transpiration. It creates a negative pressure gradient that helps draw water and minerals up through the plant from its roots. 5. See all Hide authors and affiliations. The absorbed water is transported from the roots to the leaves through the xylem vessels that are greatly influenced by transpiration pull. Transpiration pull is very important for big plants. Moreover the Transpiration pull is also said to have a role in water transport through the xylem. The … As discussed, Transpiration plays a significant role by removing excess water from the aerial parts of the plants. The water transported upwards from the roots to the leaves also contains dissolved mineral salts which are used to produce a variety of substances such as proteins in the plant. Transpiration helps to cool down the plant surface during evaporation. The process of transpiration allows all the dissolved nutrients contained in the water molecules to move from the roots to the leaves, allowing them to be rehydrated due to the water loss experienced from transpiration. Translocation: This causes the plant cells to cool down and prevents direct sunlight from damaging the delicate cells. Stomatal transpiration (through leaves) – Loss of water through specialized pores present in the lower surface of leaves called stomata.It accounts for around 80 to 90% of the total water loss from plants. Transpiration helps in the process of photosynthesis and exchange of gases. Cuticular transpiration (through leaves and stem) – The water lost through the impermeable covering present on the leaves and stem of the plant called the cuticle. Some of the water is needed in photosynthesis. Allows the movement of minerals from the soil to different parts of the plant. oProduces 90-450 kg of water for each pound of solid material produced by plants. The cohesion-tension model works like this: Transpiration (evaporation) occurs because stomata are open to allow gas exchange for photosynthesis. Wiley Online Library Richard Lee, Reply [to “Comment to ‘Further to the Hydrologic Importance of Transpiration Control’ by Stomata”], Water Resources Research, 10.1029/WR004i006p01389, 4 , 6, (1389-1390), (2010). It creates a negative pressure gradient that helps draw water and minerals up through the plant from its roots. Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. IMPORTANCE OF TRANSPIRATION . Transpiration is responsible for uptake of water from soil. Transpiration is ultimately the main driver of water movement in xylem. It supplies water for photosynthesis. If the cells lose too much water, they shrink and become flaccid and the plant becomes soft and has less support. Transpiration helps in the absorption of water from the soil. ADVERTISEMENTS: In this article, we will discuss about the role of transpiration pull in ascent of SAP. The disadvantages of transpiration are:-a)Excess of transpiration retards the growth and development of plants So plants get depleted of water due to continuous transpiration.

Transpiration is an important factor in the water cycle as it is one of the major sources of water into the atmosphere.Providing 10% of the total water in the atmosphere, this process is nearly identical to perspiration or sweating in animals. This results in a build-up of pressure called turgor pressure and the cells are said to be turgid. Helps to keep the plant cool on hot weather - a method of evaporative cooling. Transpiration is the process in which plant roots absorb water and then release the water in the form of vapour through the leaves. Roots consume some amount of water from the soil and the rest evaporates in the atmosphere. Transpiration—the loss of water vapor to the atmosphere through stomata—is a passive process, meaning that metabolic energy in the form of ATP is not required for water movement.The energy driving transpiration is the difference in energy between the water in the soil and the water in the atmosphere. Transpiration stream helps in the distribution of nutrients to all the parts of the plant body. 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. oCreates water vapor that forms into fog and clouds. Excessive rate of transpiration leads to stunted growth of plants. Curtis (1926) has rightly called that “Transpiration is a necessary evil” because of its advantages and disadvantages. It is thought that transpiration enhances nutrient uptake into plants. The Importance of Transpiration The process of transpiration is a very important procedure for plants. Transpiration is a unique feature in the plant system and referred as necessary evil as it is advantageous to plant under certain circumstances and harmful in some other situations.
