An antique spurge plant, Euphorbia antiquorum, sending out white rhizomes. In botany and dendrology, a rhizome (/ ˈ r aɪ z oʊ m / RY-zohm) [note 1] is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. [3] Rhizomes develop from axillary buds and ...
Root vegetables are underground plant parts eaten by humans or animals as food. In agricultural and culinary terminology, the term applies to true roots such as taproots and tuberous roots as well as non-roots such as bulbs , corms , rhizomes , and stem tubers .
Root vegetables are underground plant parts used as vegetables. They are called root vegetables for lack of a better generic term, but include both true roots such as tuberous roots and taproots , as well as non-roots such as tubers , rhizomes , corms , bulbs , and hypocotyls .
Aerenchyma in stem cross section of a typical wetland plant. Aerenchyma or aeriferous parenchyma [1] or lacunae, is a modification of the parenchyma to form a spongy tissue that creates spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root.

A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
A rhizome is a horizontal stem that often grows underground, usually sending out roots and shoots from its nodes. Some plants have rhizomes that grow above ground or that lie at the soil surface, including some Iris species. Usually, rhizomes have short internodes; they send out roots from the bottom of the nodes and new upward-growing shoots ...
Haustorial – specialized roots that invade other plants and absorb nutrients from those plants. Lignotuber – root tissue that allows plants to regenerate after fire or other damage. Primary – root that develop from the radicle of the embryo, and is normally the first root to emerge from the seed as it germinates.
In land plants, rhizoids are trichomes that anchor the plant to the ground. In the liverworts , they are absent or unicellular, but they are multicellular in mosses . In vascular plants , they are often called root hairs and may be unicellular or multicellular.
