Question

The water movement in taller trees like Sequoia sempervirens is mainly due to -

• A. Transpiration pull
• B. Guttation
• C. Root pressure
• D. ATP

Answer 1

The correct option is A

Transpiration pull

Sequoia sempervirens is a very tall tree. In tall trees water is pulled up from the roots and the driving force for this process is transpiration from the leaves. The suction force created by the transpirational pull helps in transporting water to the highest point of any tree. Root pressure alone can help in transporting water in short plants and trees.
