Answer
One adaptation of a root hair cell that increases the absorption of water and mineral ions is its long and thin shape. This shape increases the surface area available for absorption, allowing more water and nutrients to enter the cell from the surrounding soil. Additionally, root hair cells contain a permeable cell membrane that facilitates the efficient movement of water and minerals into the cell.
