Gravitational water
Combined water
Capillary water
Under conditions of high transpiration pull, the primary driving force for water movement through the xylem is:
Root pressure generated by active transport of ions.
Capillary action within the narrow xylem vessels.
Active transport of water molecules by xylem parenchyma cells.
Cohesion and adhesion of water molecules, creating a continuous water column.
