How does transpiration pull help in the absorption of water by plants?

Solution
Transpiration pull:
Transpiration pull, also known as suction force, is a biological mechanism in plants in which water flowed from the leaves causes a force or suction effect in the vascular bundles.
Transpiration occurs when water vapour escapes from the pores of the leaves (stomata).
This necessitates the employment of suction force in the xylem bundles, causing the water to rise.
The increased pressure causes the plant to absorb more water.
The roots take water from the plants due to the upward force, or transpiration pull.
Cohesive forces bring water molecules from the soil together. The water molecules in the xylem are likewise affected by adhesion forces.
This aids in the formation of the water column that flows upwards into the leaves. The roots absorb water as a result of this movement in the tips of the roots.
