root hair, or absorbent hair, the rhizoid of a vascular plant, is a tubular outgrowth of a trichoblast, a hair-forming cell on the epidermis of a plant root. As they are lateral extensions of a single cell and only rarely branched, they are visible to the naked eye. They are found only in the region of maturation of the root. Just prior to, and during, root hair cell development, there is elevated phosphorylase activity.
Root hair cells are outgrowths at a tip of the plant's roots. Root hair cells vary between 15 and 17 micrometres in diameter, and 80 to 1,500 micrometres in length.They are found only in the zone of maturation, and not the zone of elongation, possibly because any root hairs that arise are sheared off as the root elongates and moves through the soil.Root hairs grow quickly, at least 1μm/min, making them particularly useful for research on cell expansion.
