Rhizoids are protuberances that extend from the lower epidermal cells of bryophytes and algae. They are similar in structure and function to the root hairs of vascular land plants . Similar structures are formed by some fungi .
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 grow horizontally. The rhizome also retains the ability to allow new shoots ...
These stolon-like rhizomes are long and thin, with long internodes and indeterminate growth with lateral buds at the node, which mostly remain dormant. [ citation needed ] In potatoes , the stolons [ 15 ] start to grow within 10 days of plants emerging above ground, with tubers usually beginning to form on the end of the stolons. [ 16 ]
Rhizome – a horizontally orientated, prostrate stem with reduced scale-like leaves, normally growing under ground but also on the soil surface. Also produced by some species that grow in trees or water. Rootstock – the underground part of a plant normally referring to a caudex or rhizome.
Rhizome: A horizontal underground stem that functions mainly in reproduction but also in storage, e.g. most ferns, iris. Runner: A type of stolon, horizontally growing on top of the ground and rooting at the nodes, aids in reproduction. e.g. garden strawberry, Chlorophytum comosum.
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 may be broken, shattered at a given spot, but it will start up again on one of its old lines, or on new lines" "5 and 6. Principle of cartography and decalcomania: a rhizome is not amenable to any structural or generative model. It is a stranger to any idea of genetic axis or deep structure."
Nitrogen fixation is one of the most beneficial processes performed by rhizobacteria. Nitrogen is a vital nutrient to plants and gaseous nitrogen (N 2) is not available to them due to the high energy required to break the triple bonds between the two atoms. [4]
