Please answer in detail ...............!​

Answer 1

☣Answer

➡Transpiration pull(It is based on the upward movement of water from the root to aerial parts of the plant body which is called as ascent of sap or often called translocation of water).

Water molecules stick to one another through cohesion forming a column in the xylem helps plants to absorb water from the soil.

➡Plants need energy so, they have to open up and allow transpiration to happen. While they loose water, they gain energy.

Loosing water can be considered as paying and gaining energy in place of that.
