root hairs
Tiny plant extensions
Root hairs are tiny, finger-like extensions that grow from the surface of plant roots.
Each hair is a single elongated cell that dramatically increases the root's surface area for absorbing water and nutrients from soil.
They form a fuzzy coating on young roots: The seedling's root hairs were visible under magnification.
