Question

list any four mechanisms that contribute to the ascent of sap in tall trees​

Answer 1

Answer:

The theory states that transpiration pull or tension, cohesion property of water, and hydration of the cell walls (i.e., adhesion) are collectively responsible for the ascent of sap. Water movement through the xylem is a bulk flow caused by ΔΨp (pressure difference) between one end of the system and the other.
