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.
A fibrous root system (sometimes also called adventitious root system) is the opposite of a tap root system. It is usually formed by thin, moderately branching roots growing from the stem.
A fibrous root system is universal in monocotyledonous plants and ferns, and is also common in dicotyledonous plants.

Adventitious roots develop on stems, leaves and even old roots. The radicle or primary root and its lateral roots are the only nonadventitious roots. Many aerial stems naturally form aerial roots. There are two types of adventitious roots. Aerial stems often have preformed root initials at nodes that will develop into roots given the proper conditions. Other adventitious roots are termed wound roots, because they do not form until the stem, root or leaf is wounded.
Root nodules occur on the roots of plants that associate with symbiotic bacteria.
Under nitrogen limiting conditions, plants from the pea family Fabaceae form a symbiotic relationship with a host-specific strain of bacteria known as rhizobia.
Aerial roots are roots above the ground. They are almost always adventitious. They are found in diverse plant species, including epiphytes such as orchids, tropical coastal swamp trees such as mangroves, the resourceful banyan trees, the warm-temperate rainforest rātā (Metrosideros robusta) and pōhutukawa (M. excelsa) trees of New Zealand and vines like Common Ivy (Hedera helix) and poison ivy (Toxicodendron radicans).
