Question

what is root pressure ? explain with an experiment​

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.

Root pressure is the force that drives water and nutrients into xylem upwards through plants. An experiment that can be used to demonstrate this force is by simply cutting a potted plant near the ground level and what is seen is water gushing out from the decapitated plant.
