The term "tuber" is often used imprecisely and is sometimes applied to plants with rhizomes. The plant uses the rhizome to store starches, proteins, and other nutrients. These nutrients become useful for the plant when new shoots must be formed or when the plant dies back for the winter. [4] If a rhizome is separated, each piece may be able to ...
Freshly dug sweet potato plants with tubers Hemerocallis tuber roots. A root tuber, tuberous root or storage root is a modified lateral root, enlarged to function as a storage organ. The enlarged area of the tuber can be produced at the end or middle of a root or involve the entire root.
The plants usually have underground rhizomes or tubers. The leaves are arranged in two rows with the petioles having a sheathing base. The leaf blade is narrow or broad with pinnate veins running parallel to the midrib. The petiole may be winged, and swollen into a pulvinus at the base. [citation needed]
This category contains the native flora of Arizona as defined by the World Geographical Scheme for Recording Plant Distributions. Taxa of the lowest rank are always included; taxa of higher ranks (e.g. genus) are only included if monotypic or endemic. Include taxa here that are endemic or have restricted distributions (e.g. only a few countries).
Tubers develop from either the stem or the root. Stem tubers grow from rhizomes or runners that swell from storing nutrients while root tubers propagate from roots that are modified to store nutrients and get too large and produce a new plant. [22] Examples of stem tubers are potatoes and yams and examples of root tubers are sweet potatoes and ...
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.
The plant foliage is very tough and fibrous and is often mistaken for a grass. The roots are an extensive and complex system of fine, fibrous roots and scaly rhizomes with small, hard, spherical tubers and basal bulbs attached. The tubers are 0.3–2.5 cm (1 ⁄ 8 –1 in) in diameter and the colors vary between yellow, brown, and black.
The plants often grow together in crowded colonies and spread by runners at or just under the soil surface. In late summer the plants produce tubers that are twice as long as wide, [9] each typically measuring 0.5 to 5 cm (1 ⁄ 4 to 2 in) in diameter. [8] The plant produces rosettes of leaves and an inflorescence on a long rigid scape.
