Plant roots are adapted for substance exchange through root hair cells, which develop into long extensions that greatly increase the surface area for absorbing water and mineral ions from the soil.
Plant roots have root hair cells that grow into long hairs, significantly increasing the surface area for absorbing water and mineral ions from the soil.

| Back | The cells on the surface of plant roots grow into long hairs which stick out into the soil. Each branch of a root will be covered in millions of hairs, giving the plant a large surface area for absorbing water and mineral ions from the soil. |
