Which statement accurately describes corms?

Corms are indeed thick, compact, and fleshy stems that serve as a storage organ for nutrients and energy. Unlike roots, which typically absorb water and nutrients from the soil, corms function as a part of the plant's stem system, providing support and energy reserves. They are usually found underground and can give rise to new shoots and roots, allowing the plant to survive adverse conditions and regrow in favorable seasons. This characteristic is particularly important for plants that require adaptation to seasonal growth cycles.

The other statements do not accurately describe corms. For instance, corms are not roots; they have a different structure, indicating that they are part of the stem system. Additionally, they are not modified leaves but specialized stems. Finally, corms are not specifically associated with aquatic plants; they can be found in various environments, primarily in garden and field settings where plants have evolved to use corms for survival and propagation.
