The root system provide fixation or anchorage for the plant into the soil.
Absorption of water and mineral salts from the soil is carried out by the root.
The root conducts the absorbed water and mineral salts from the root hairs to the rest of the plant body. This function is performed through cortex, endodermis and xylem.
Food materials are stored in the roots of many plants., This is done in the parenchyma cells of the cortex. Thus the morphology and anatomy of the root is well suited to carryout its basic function.
