Describe how a root hair cell is adapted
WebRoot meristem adds cells to root cap and the basal region of the root. (c) Zone of elongation: It is about 1-10 mm long and lies just behind the meristematic zone. As the name implies, it is the site of rapid and extensive cell elongation. This zone increases length of the root. The external cells can absorb water and minerals from the soil. WebRoot hair cells are adapted for this by having a large surface area to speed up osmosis. The absorbed water is transported through the roots to the rest of the plant where it is …
