Question

is transpiratiomal pull is essentail for conducting water in plants​

Answer 1

yes in plants it helps them to condict water in upward direction

Answer 2

We know that $\textbf{Transpiration}$ is actually lost of 90% of absorbed water in the form of water vapour fron different aerial parts of plants.

It helps the plants in the following ways :

1. It provides cooling effect.

This cooling effect is due to released water vapour in atmosphere.

2. It helps Xylem to conduct water upwards.

The loss of water by plants through leaves creates a suction which pulls water from xylem cells of roots, due to pressure difference.

Means, yes transpirational pull is essential for conducting water in plants.
