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.
Since the hypocotyl is a region between the stem and the roots, such tubers are variable in their anatomy and growth habits. Thus the roots of Cyclamen graecum grow from the base of the tuber, suggesting it is a stem tuber, whereas those of Cyclamen hederifolium mostly grow from the upper surface of the tuber, suggesting it is a root tuber. [10]
The tuber produces roots from the center of the bottom only. [3] It remains small, only reaching about 6.5 cm (2.6 in) across. The leaves are round or kidney-shaped to long heart-shaped. The color is all-silver, all-green, or silver variegated with a variably sized green hastate (arrowhead-shaped) or "Christmas tree" pattern and a green edge.
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.
A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. [10] In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to plants with rhizomes.
The underground part is a tuber — a swollen, food-storage stem, much like an Irish potato. This edible tuber has 'roots' in Caribbean nations | Mystery Plant Skip to main content
Flowers and leaves come from buds at the top of a round-flattened tuber. Roots come from the sides and bottom. Older tubers may become distorted, forming "fingers" with separate growth points. [5] Misshapen tubers are also found in Cyclamen rohlfsianum.
The root of this plant produces a large edible tuber that can be as much as 75 cm (30 in) long and 12 cm (5 in) thick, weighing up to 10 kg (22 lb)., [5] with other sources alleging even larger sizes. [6] This can be roasted and eaten, resembling a sweet potato, young specimens being best as older tubers may be bitter. Other uses for the plant ...
