Xylem sap and soil water differ in solute composition because of selective uptake by the endodermis
Explanation:
xylem sap is made up of water, minerals and plant hormones.
soil water is of three types as gravitational, capillary and hygroscopic water.
It consist of water which is an important source for carrying water and nutrients to other part of the plant.
Due to the transpiration and evaporation the pressure in the leaf xylem decreases and causes upward pull of xylem sap.
Endodermis is a waterproof partition in xylem cells and does not let water diffuse back. This allows selective uptake of solutes.
