Explain the cohesion tension theory and its importance for water flow in plants
Homework Answers
transport of water from the roots to the shoots,through the xylem against gravity, is explained by cohesion tension theory.
water molecules have the property of cohesion, that is molecules of the water attract each other.
According to cohesion-tension theory. water from the plant is lost through the stomata, water vapour is lost through the stomata, of the leaves creating a negative pressure of the water in the leaves, so tension is created in the leaves which pulls the water towards the leaves, since water has the cohesive property a column of water forms in the xylem, so the water is transported from the roots to the shoots based on the transpiration rate. that is water is transported due to the tension created by transpiration and the cohesive property of the water.

Briefly outline the Transpiration Adhesion Cohesion Tension Model of water movement in plants. Use the model to describe where and how a water molecule moves though a vascular plant -- from when it is first pulled into the root until it exits a leaf stoma.
