The root hairs are filament like projections of the epidermal outer layer cells. These root hairs, in conjunction with the cells of the filamentous root fibers, are responsible for the vast majority of water and nutrient uptake. Each root cell, as is the case in all plant cells, is surrounded by a porous cell wall.

The concentration of mineral ions inside the plant's roots is a lot higher than that found in the soil. Therefore, mineral ions have to be transported into the roots via active transport. Protein pumps exist in the plasma membranes of root cells. There are many types of these protein pumps for the absorption of many different mineral ions.

Water and minerals are absorbed from the soil by roots and then transported to various parts of the plant like stem, leaves and flowers, etc. Soil particles, which are coated with water and dissolved minerals, adhere to the root hairs. The soil solution flows into the epidermal cells of the root hairs and reach the root cortex.

In plants and animals, mineral absorption, also called mineral uptake is the way in which minerals enter the cellular material, typically following the same pathway as water. In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse inbetween the cells. In contrast to water, some minerals are actively taken up by plant cells.
