A plant's taproot is a straight tapering root that grows vertically down. It forms a center from which other roots sprout.

Plants with taproots are difficult to transplant.

The taproot is why dandelions are hard to uproot — the top is pulled, but the long taproot stays in the ground, and re-sprouts.

A taproot system contrasts to a fibrous root system, with many branched roots.

Most trees begin life with a taproot, but after one to a few years change to a wide-spreading fibrous root system with mainly horizontal surface roots and only a few vertical, deep anchoring roots. A typical mature tree 30-50 m tall has a root system that extends horizontally in all directions as far as the tree is tall or more, but well over 95% of the roots are in the top 50 cm depth of soil.
