Question

write a short notes on 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.

Root pressure is a force or the hydrostatic pressure generated in the roots that help in driving the fluids and other ions from the soil in upwards directions into the plant's vascular tissue – Xylem. This process is produced by osmotic pressure in the cells of the root.
