Role of Transpiration Pull in Plants
Transpiration pull is an important physiological process in plants. The role of transpiration pull in plants is cited below:
- Water Absorption and Transport: The plants absorb water along with nutrients from the soil and transport them to different parts of the plant body with the help of transpiration pull.
- Water Balance: It helps to release excess water from the plant body and maintain a proper balance of water in plants.
- Photosynthesis: It helps in the upward movement of water from the roots to the leaves through xylem tissues. This water is used in photosynthesis.
- Gaseous Exchange: It helps gaseous exchange in plants during photosynthesis.
- Cell Turgidity and Osmotic Pressure: It helps in maintaining cell turgidity and osmotic pressure.
- Cooling the Plant Body: It helps in cooling the plant body by evaporation of water from the leaves.
- Growth and Development of Plants: It helps in the proper growth and development of plants by maintaining proper water balance in the body.
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.
