Discuss the cohesion tension theory for uptake of water in plants.
Answers
The cohesion-tension theory is a theory of intermolecular attraction that explains the process of water flow upwards (against the force of gravity) through the xylem of plants. Transpiration pull, utilizing capillary action and the inherent surface tension of water, is the primary mechanism of water movement in plants.
Cohesion tension theory:
Cohesion happens when water atoms adhere to one another. Union causes the water in the container of the root and stem to become one long segment of liquid and supplements. As water dissipates from the plant into the air called transpiration in plants, the section of water keeps on climbing to fill the space left by the water particles that were "hauled out" of the leaves through evaporation.
Because the sun warms the water inside the leaves, making the water dissipate. At the point when the sun warms the water in plant leaves, it brings about transpiration; however it allows photosynthesis.
