Question

Paheli noticed water being pulled up by a motor pump to an overhead tank of a five-storeyed building. She wondered how water moves up to great heights in the tall trees standing next to the building. Can you tell me why?

Answer 1

Transpiration pull:

1. Roots regularly absorb minerals and water from the ground.
2. Evaporation of water from leaves creates the suction force.
3. It aids with the upward movement of water and can reach vast heights in tall trees.
4. A transpiration pull can be simply defined as a biological process in which a pulling force is generated within the xylem tissue.
5. The upward migration of water into the xylem vessels is aided by this force.
6. The loss of water in the form of vapours via the leaves is noted during this phase.
7. All higher plants and trees go through this biological process because their stems are encircled by bundles of fine tubes formed of a woody material called xylem.
