People often use tuber to refer to any plant structure with rounded or wart-like prominences, but botanically, true tubers are actually modified plant stems, not roots, even though they're found underground. Potatoes are the most common example of true tubers.
Is potato a stem vegetable?
Potatoes grow at the end of the stolon, or underground stem. The potato is classified as a stem because it has several nodes, known as eyes, and space between each eye, known as internodes. The potato's eye can grow into a shoot and a new plant. As a result, it is a vegetable with stems.
Is potato a storage root?
Potato is definitely not a root, and it's not really a stem. It's a modified stem known as a tuber. Tubers develop from an underground stem known as a stolon, and they act as storage for food/starch for later use by the plant.
Is potato a rhizome?
A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. 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.
