Give reason why the xylem sap flows out from the cut end if a well hydrated plant is cut below the first leaf or near the base of stem.


#2

Flow of xylem sap through the cut end is called exudation. It occurs due to hydrostatic pressure developed in the root system by the accumulation of water absorbed by the root cells. Such pressure is called root pressure.
