root hair

Plant's water straw

A root hair is a thin, tube-like outgrowth from a plant root's surface that absorbs water and minerals from soil.

These microscopic extensions vastly increase the root's surface area, making nutrient uptake more efficient.

Root hairs are delicate and short-lived, continuously replaced as the root grows deeper.
