Question

Which of the following contributes most to transport of water from the ground to the leaves of a tall tree?

• A. Breakdown of ATP.
• B. Cohesion of water and transpiration pull.
• C. Root pressure.
• D. Capillary rise of water in xylem.

Answer 1

The correct option is B

Cohesion of water and transpiration pull.

Cohesion of water and transpiration pull contributes most to transport of water from the ground to the leaves of a tall tree. The property of water molecules getting attracted to other water molecules which is known as cohesion and the suction force produced by the upward pull of water helps to transport water to the leaves from the ground.
