Actually, most water and nutrients are absorbed by 'roots hairs',a hair-forming cell on the epidermis of a plant root. Therefore, plants have developed an effective system to absorb, translocate, store and utilize water. Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca.
