Answer 1

Answer:

Transpiration pull is the force which helps movement of water from roots of the plants to leaves.

Explanation:

A transpiration pull could be simply defined as a biological process in which the force of pulling is produced inside the xylem tissue. This force helps in the upward movement of water into the xylem vessels. In this process, loss of water in the form of vapours through leaves are observed. This biological process is carried out in all higher plants and trees as their stems are surrounded by bundles of fine tubes, which are made from a woody material known as xylem.

Transpiration pull is also referred as suction force and this force is used to draw the water in an upward direction from the roots to the leaves. The amount of water received by the leaves are used for the photosynthesis and the excess amount of water is released into the atmosphere in the form of vapours through the openings in the leaves known as stomata.
