Question

the concentration of minerals is more inside the root hair than in the soil,still root hair absorbs them why​

Answer 1

Answer:

Water is absorbed by the root hair cell by the preocess called, Osmosis. Osmosis is the phenomenon where solute moves from higher concentration to lower concentration against a semi-permeable membrane. Water  passes from a region of high water concentration (wet soil) through a  semi-permeable membrane (the cell membrane) to a region of lower water  concentration (the cytoplasm).  

Root hairs are made up of epidermal cells, which are present on the surface of the root, they also  increase the surface area for absorption. They absorb  minerals by  active transport and water by osmosis. These substances then move to the  xylem.

Answer 2

Answer:

The concentration of mineral nutrient elements is higher inside the root-hairs than in the surrounding soil because the absorption of mineral elements from the soil involves active transport by the cells. As the concentration of ions always maintained greater inside the root hair water present in the surrounding soil moves into the roots by osmosis. This dilute solution of water and mineral salts, absorbed from the soil by the roots, can be used for food manufacture in the leaves, only if it can travel up to the highest points of the plant. This upward flow occurs through the xylem.
