A stem of a plant which grows underground in a horizontal manner producing roots and shoots at the nodes. Once these shoots establish the rhizome may be severed and the new plants will survive. Some rhizomes may also store food for the plant. See also Stolon.
A rhizome is essentially a stem that is trying to do the work of a root. Early plants did not have specialised roots, but by developing root hairs on their stems, and growing those stems across the floor, they were able to support themselves and absorb water from the soil. Some plants still have rhizomes - ferns, tree ferns, iris and some grasses.
Rhizomes are not roots, though they may look like them; they are underground stems. Instead of growing down, like roots generally do, rhizomes grow horizontally. Roots can grow from the rhizome, as can leaves, flowers, and other stems. Quack grass, for examples, spreads quickly using its rhyizomes.
A rhizome is a modified stem that has nodes and internodes that grows at ground level or just below ground level. It is thickened because of food storage. Stems or leaves branch off the rhizome at the nodes. Roots form by adventitious buds along the lower surface. Thus, it acts like a perennial rootstock. A good example is an iris or fern rhizome.

root stock. Used by post-structural theorists in a philosophical context (see for example, Gilles Deleuze and Felix Guattari, "Introduction: Rhizome," A Thousand Plateaus: Capitalism and Schizophrenia, Brian Massumi, trans., University of Minnesota Press 1987) to describe principles for organizing knowledge, among other things. Without any reference to philosophy, the term was reactivated to describe the ideological superstructure of the New Economy. Under this term, decentralization of social and corporate structures was propagated. In 2010, Bill Gates founded the Deleuze Prize, when he and his company were yet again the defendants in another anti-trust trial.
A plant organ which resembles a horizontal stem from which leaves grow. Anubias and Java Fern are common aquarium plants which grow from a rhizome. It is important that the rhizome lies on top of the substrate and is not buried within it as roots usually are, otherwise it will rot and the plant will die.

a rootlike plant stem that grows under the earth, roughly parallel to the surface of the ground, and sends out at intervals along its length roots reaching downward and vertical stems with leaves and flowers that extend above the earth
a horizontal or upright stem found underground or growing across the surface of the substrate, modified for reproduction or for food storage. It is particularly apparent in the rapid underground spread of many grasses.
A fleshy stem, usually (but not always) horizontal and underground, that lasts for more than one growing season and is often a storage organ. A rhizome normally produces subterranean feeding roots as well as top growth.
An underground, horizontal plant stem that produces shoots above and roots below, and is distinguished from a true root in possessing buds, nodes, and usually scale-like leaves. Rhizosphere: The soil surrounding and directly influenced by plant roots.
the living portion of bamboo, the rhizome stores energy & nutrients for the following season's growth and it is the portion of the underground system that must be prevented from spreading where 'unwelcome'
A somewhat elongated, usually horizontal, subterranean plant stem that is often thickened by deposits of reserve food material, produces shoots above and roots below, and is distinguished from a true root in possessing buds, nodes, and usually scale-like leaves ( Merriam-Webster).
a food-storing branch of the underground system of growth in bamboos from buds of which culms emerge above ground. Popularly known as rootstock, rhizomes are basically of two forms: sympodial (tropical, clumping, Pachimorph) and monopodial (temperate, running, Leptomorph).
A horizontal, usually underground stem that often sends out roots and shoots from its nodes (a knot or bulge on the plant root or shoot). Buds that form at the joints produce new shoots and can become new plants; also called rootstalk or rootstock.
n. A horizontal underground stem, such as found in many ferns, where only the leaves may stick up into the air; sphenophytes (horsetails and their relatives) spread via rhizomes, but also produce erect stems.
A horizontal stem that grows shallowly underground. At nodes along the rhizome, below-ground roots and above-ground shoots grow into new plants. Examples include strawberries and many types of grasses.
An underground rootlike stem; it usually grows horizontally, is often thickened by deposits of reserve food material, produces shoots above and roots below, and is distinguished from a true root because it possesses buds, nodes, or scalelike leaves.
A rhizome is a thick, horizontal underground stem (not a root) of a plant, that grows close to the ground. Rhizomes have nodes and scale-like leaves; roots form on the lower surface and new shoots can form at nodes. Ferns, mosses, horsetails, ginger, irises, and some grasses have rhizomes.
A rhizome is, in botany, a usually underground, horizontal stem of a plant that often sends out roots and shoots from its nodes. Rhizomes may also be referred to as creeping rootstalks, or rootstocks. A stolon is similar to a rhizome, but exists above ground, sprouting from an existing stem.
