The force responsible for the movement of water across the root in the passive absorption of water operates in Leaves.
Passive absorption occurs when the rate of transpiration is typically higher than normal. Rapid evaporation of water from the leaves during transpiration causes a buildup of water in the xylem of the leaves, which results in a buildup of pressure.
Root pressure, in plants, is the force that helps to drive fluids upward into the water-conducting vessels (xylem). It is primarily generated by osmotic pressure in the cells of the roots and can be demonstrated by the exudation of fluid when the stem is cut off just aboveground.
