root pressure theory class 10

Difference between single and double circulation in human being. What is root pressure theory? Root Pressure Theory: Protagonists of this theory believed that all plant roots absorb excess of water by an active process and builds up a hydrostatic pressure within the root system, called root pressure. - wherein. By this process plants get water at their top most part even during night . First of all it is important to know that why is RPT required . Root pressure is not common among trees of the Temperate Zone and occurs chiefly in the spring before leaves develop and transpiration is rapid.

When transpiration is high, xylem sap is usually under tension, rather than under pressure, due to transpirational pull. 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. The quantities of water moving upwards through the xylem by root pressure are, however, very small … This can be observed when a freshly cut root stump continues to exude sap from its xylem vessels.
