What is Root hair?
[[File:NSRW Root-Tip.png|thumb|100px|Drawing of [[root tip]], showing young root hairs]] A '''root hair''' of a [[vascular plant]], is a tubular outgrowth of a hair-forming cell on the [[epidermis]] of a plant [[root]]. They are lateral extensions of a single cell, and invisible to the naked eye and light microscope. The function of root hairs is to collect [[water]] and mineral [[nutrients]] from the soil. This solution goes up through the roots to the rest of the plant. Root hair cells survive for 2 to 3 weeks and then die off. New root hair cells are continually being formed at the tip of the root. This way, the root hair coverage stays the same.A '''root hair''' of a [[vascular plant]], is a tubular outgrowth of a hair-forming cell on the [[epidermis]] of a plant [[root]].
