Question

what is root pressure​

Answer 1

Answer:

Root pressure 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

Root pressure is defined as hydrostatic pressure developed in the root due to the accumulation of absorbed water. The pressure exerted on the liquid contents of the cortical cells of the roots, under fully turgid condition this root pressure pushes the water up the xylem vessels to the aerial parts.
