This has been specially devised to give a one-to-one learning experience JUST LIKE YOUR SCHOOL or TUITION. Root Pressure Theory(RPT) - It is a phenomena by which plants get water during night . Grapevines, for example, are capable of showing fairly high root pressure (about 5 or 6 bars), yet no one considers root pressure as a mechanism for the translocation of water in tall trees. This theory is unacceptable because ascent of sap was also observed in plants in which roots were removed. This activity pushes the water upwards all along the length of the stem. 1.

A root pressure of 1 to 2 atmospheres has been reported in a number of cases. Root pressure is the pressure which is set up in the cortical cells of the roots due to osmotic action and forces water up the xylem vessel. Class 11: Biology: Long Distance Transport of Water: Root Pressure Theory What is root pressure theory? Log in. 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. This pressure, which is a push from below arid not due to any tension developed in the xylem vessels due to transpiration and which seems to originate in roots has been termed root pressure. It is primarily generated by osmotic pressure in the cells of the roots and can be demonstrated by exudation of fluid when the stem is cut off just aboveground. 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.
