Question

transpiration helps in ascent of sap give reason

Answer 1

Heya !!!!☺

It is responsible for absorption of major quantity of water by roots by way of passive mechanism without requiring energy in the form of ATP. Transpiration pull initiates the large scale movement of water form soil into root xylem and then upwards to all aerial parts (ascent of sap)

Answer 2

transpiration causes the loss of water from the plant body thus decreases the concentration of water and minerals inside the plant body this creates a transpirational pull which helps in the upward movement of sap
hope it helps
