Conclusion – An Overview of Transpiration Pull in Plants
Transpiration is the main cause of the development of transpiration pull. The suction force or pull generated during transpiration draws the water along with nutrients from the soil to enter the roots and then transfer to the xylem vessels. A negative hydrostatic pressure works during this transfer of water from the roots to the leaves. The stronger cohesive force of water molecules helps to establish a capillary action that prevents the breakage of the water column throughout the xylem vessels. Thus, a continuous flow of water and nutrients takes place through the xylem tissue.
Transpiration Pull in Plants
An overview of transpiration pull in plants describes the details of transpiration pull, a physiological process that helps the plants pull the water from the soil to the leaves by a force generated within the xylem. This process starts when the stomatal opening of the leaf allows water and carbon dioxide to enter the plant.
As photosynthesis happens, water vapor is released through the leaf, causing a drop in air pressure within the leaf. This negative air pressure aids the water molecules to reach the leaf through the stem. In this article, we will look into transpiration pull – meaning, phenomenon, factors affecting, and significance of transpirational pull in plants.
