Briefly explain, how transpiration helps in the upward conduction of water in plants​

Answer 1

Your answer......

As when transpiration occurs it creates a gap of vaccum between the xylem tissue and leave's mesophyll cells which has to be fill up .

so as the pressure decreases in that gap of vaccum the water from trachieds reaches the mesophyll cells..

This is because as you know that solvent flows from high concentration to low concentration .

Therefore as low concentration is formed in the gap the water gradually reaches up.....
