Many plants have underground modified stems that may be mistaken for roots. Examples of underground stems include corms, such as taro (left); rhizomes, such as ginger (center); and tubers, such as potatoes (right).

Underground stems are modified plants that derive from stem tissue but exist under the soil surface. The roots are modified to have root hairs and branch indiscriminately with cells that take in water and nutrients, while the stems are modified to move water and nutrients to and from the leaves and flowers.

The root vegetables include beets, carrots, radishes, sweet potatoes, and turnips. Stem vegetables include asparagus and kohlrabi. Among the edible tubers, or underground stems, are potatoes. The leaf and leafstalk vegetables include brussels sprouts, cabbage, celery, lettuce, rhubarb, and spinach.

Potato grows on the end of the underground stem known as the stolon. Sweet potato: The biological name of sweet potato is Ipomea batatas. It belongs to the morning glory family. – These plants have adventitious root modifications called tuberous roots.

Potatoes and yams technically have modified belowground stems (“stem tubers”) while sweet potatoes have “root tubers.”

The plant reproduces in three ways: from seed, from the actual storage roots, or from the plant vines. Sweetpotato is cultivated by vegetative propagation. Growers take stem cuttings from the vines, which then root and form new storage roots.
