Answer:
Active osmotic water absorption
The root cells behave as an ideal osmotic pressure system through which water moves up from the soil solution to the root xylem along an increasing gradient of D.P.D. (suction pressure, which is the real force for water absorption). ... This gradient of water potential causes endosmosis.
