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.
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 .

[5] Almost all parts of some species have been developed for food, including the root (swede, turnip), stems (), leaves (cabbage, collard greens, kale), flowers (cauliflower, broccoli, romanesco broccoli), buds (Brussels sprouts, cabbage), and seeds (many, including mustard seed, and oil ...

Plants have root systems that are fibrous and shallow. [8] About 90% of the root mass is in the upper 20–30 cm (8–12 in) of soil; some lateral roots can penetrate up to 2 m (6 + 1 ⁄ 2 ft) deep. [6] The inflorescence is an unbranched and indeterminate terminal raceme measuring 50–100 cm (20–40 in) tall, [6] with flowers that are yellow ...
The fibrous-root system (A) is characterized by many roots with similar sizes. In contrast, plants that use the taproot system (B) grow a main root, with smaller roots branching off. The letters indicate where the root systems begin. A taproot is a large, central, and dominant root from which other roots sprout
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. It is thus different in origin, but similar in function and appearance, to a stem tuber.
