Root hair tissue

WebAs the root matures, the root hairs are lost from the epidermis. These areas of the root now function for anchorage and transportation of water. Because these areas are no longer taking up water, the vascular cylinder is sealed off by a waxy layer of suberin that covers the endodermis called the casparian strip. WebRoot hairs perform multiple key functions in the plant growth and developmental process, notable among which is absorption and subsequent transfer of water, nutrients, and minerals from soils, plant-microbe interactions, and sequestration of toxic metals in selected cases ( Datta et al., 2011 ).
