<span>Root hairs and all active transport mineral ions are used by plants to enable water absorption. The route of the movement of water inside the root would be illustrated through this sequence:Epidermis (outside layer of the roots) --> cortex (ground tissue layer just between the epidermis and the root's vascular tissue) --> endodermis(a layer outside the vascular tissue;responsible for mineral uptake of plants) --> stele( tissues combined inside the cortex) --> xylem (can be primary and secondary, both originates from provascular tissue and vascular cambium,maturing to its inside, respectively) --> phloem (can be primary and secondary too, both originates from provascular tissue and vascular cambium,maturing to its outside, respectively --> cambium(a meristem originating from an apical meristem, gives rise to secondary xylem and secondary phloem. </span>
