Adventitious roots
In vascular plants, the root is the organ of a plant that typically lies below the surface of the soil. This is not always the case, however, since a root can also be aerial or aerating . Furthermore, a stem normally...


adventitious roots -- A root that grows from somewhere other than the primary root, for example, roots that arise from stems or leaves.

adventitious roots Roots that develop from the stem following the death of the primary root. Branches from the adventitious roots form a fibrous root system in which all roots are about the same size; occur in monocots.

Adventitious roots arise out-of-sequence from the more usual root formation of branches of a primary root, and instead originate from the stem, branches, leaves, or old woody roots.

Adventitious Roots. Both taproots and fibrous roots are root systems that arise at the base of the plant shoot during germination.

prop roots Adventitious roots arising on a stem above the ground and imparting some mechanical support to plants. The angled roots may provide for absorption of water and nutrients.
propagation The process of increasing in number.

Auxin also stimulates the formation of adventitious roots in many species. Adventitious roots grow from stems or leaves rather than from the regular root system of the plant.

Problem : Describe taproots, fibrous roots, and adventitious roots. How are they different?
