Root pressure is 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--- the pressure that forces water, absorbed from the soil, to move through the roots and up the stem of a plant. ..this pressure can be demonstrated by cutting a stem, from which water will exude... a manometercan be attached to a plant stem to measure the root pressure...
