Question

Explain how water moves up a plant via transpiration?

Answer 1

Hint: When the water is absorbed by the roots of a plant then it reaches the leaves and it further escapes through the stomata along with the other wastes which are present.
The basic role of transpiration is to facilitate the upward motion of the water in vascular bundles. As the water moves in the upward direction, it is simultaneously lost through the leaves and it is lost in the form of water vapour.

Complete answer:
Transpiration pull is also well known as the suction force. It is a biological process which takes place in the plants through which a force is produced in the vascular bundles when the water is being transpired from the leaves.

Transpiration takes place when the water escapes from the stomata in the form of water vapour. Thus, when this process happens, then this creates a need for the transpiration force in the xylem bundles which helps the water to move in upward direction. This pressure which is created, results in more and more uptake of the water by the plant. This transpiration pull also causes the roots to absorb more water from the plants.

Water molecules which are present in the soil combine due to cohesive forces. The adhesive forces also act inside these water molecules present in the xylem. This further helps in forming the column of water which moves in the upward direction in the leaves. This movement is basically produced in the tips of the roots that further results in the roots to absorb even more water.

Note:
Transpiration is a very important process that takes place in the plants. It is the process that accounts for the loss of the huge amount of water. But at the same time, this process also helps in keeping the body of the plant cool. It also ensures that an uninterrupted flow of water and nutrients continues in the plants, which further helps in preventing embolism. Such a type of cycle is not even possible without the transpiration process.
