In eudicots, the primary root that emerges from a seed becomes a taproot, which is a thickened, central root that grows deeper into the soil to anchor the plant and absorb water and nutrients. This is in contrast to fibrous root systems, which are characteristic of monocots and consist of many slender, branching roots that spread out horizontally near the surface of the soil. Secondary roots, adventitious roots, and lateral roots can all develop from the taproot as the plant grows, but initially, the primary root is a taproot.
