WebApr 5, 2024 · Root pressure can be defined as a force or the hydrostatic pressure generated in the roots that help drive fluids and other ions out of the soil up into the plant’s vascular tissue – Xylem. This process is produced through osmotic pressure in the stem cells. WebThe root pressure is the pressure which is exerted on the liquid contents of the fully turgid cortex cells of the root, forcing some of it into the xylem vessels and up through the stem. It is a vital phenomenon and depends upon the activity of the living cells of the root. WebApr 5, 2024 · Root pressure can be defined as the transverse osmotic pressure in the cells of a root system, which raises the sap in the stem of a plant to the leaves.
