The part of the root that provides the absorption of nutrients from the soil.

The soil provides the plant with minerals, as well as water in which they dissolve. Minerals that are dissolved in water enter the stems, leaves and other aerial parts of the plant through the root. The root, in turn, consists of four main parts: the division zone, the growth zone, the absorption zone, and the conduction zone. The absorption of water with minerals dissolved in it occurs through the root hairs. These are outgrowths, each of which is formed from one cell in the outer layer of the root – the root bark.
