Question

Explain root pressure​

Answer 1

Answer:

Root Pressure'. It is the transverse osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves. Root pressure occurs in the xylem of some vascular plants when the soil moisture level is high either at night or when transpiration is low during the day.

Answer 2

Answer:

As various ions from the soil are actively transported into the vascular tissues of the roots, water follows and increases the pressure inside the xylem. This positive pressure is called root pressure.
