(A) Transpiration creates a negative pressure or tension in the xylem vessels,which pulls the water column upward from the roots to the leaves. This is known as the cohesion-tension-transpiration pull model.Root pressure is a positive pressure that develops in the roots due to the active accumulation of ions,which pushes water upward into the xylem vessels. Therefore,transpiration acts as a pulling force,and root pressure acts as a pushing force.
