A thin hairlike outgrowth of an epidermal cell of a plant root that absorbs water and minerals from the soil.

root hair

a hair-like outgrowth from the epidermis of roots. Root hairs occur in large numbers in a zone behind the growing tip, are short-lived, and greatly increase the absorbing area of the root.

Organic anion release can also increase the availability of soil P (see later discussion); however, the location of organic anion release differs between the 2 mechanisms (Barcelo and Poschenrieder 2002)--for Al-tolerance the organic anions are released from the root tip, and for P deficiency the organic anions are normally released from the root hair zone or from proteoid roots.
