  5. Secondary roots are not as thick and tend to grow sidewards. Root hair section, part of the root on which the root hairs are located, they absorb water and nutrients from the soil. The primary root is the thickest and grows downwards. Elongation section, set of cells that determine the growth of the root. Root cap Parts of a root

  6. Taproot A main root that grows vertically into the soil.

  7. Fibrous roots Root formed in bundles where it is not possible to determine the primary root.
