Plant root hairs increase the roots surface area enabling it to absorb more water and nutrients. Now, researchers have discovered how the hairs grow straight and long. To develop an elongated structure, cell expansion on the sides of the root hair must be suppressed as the tip elongates. If it wasn't for the suppression mechanism, the root would bulge out like a balloon and be unable to form the elongated tubular structure.
