Which term describes plant structures such as stolons, tubers, rhizomes, bulbs, and corms?

• A. Leaves
• B. Specialized stems
• C. Roots
• D. Flowers

Answer: (B)

Stolons, tubers, rhizomes, bulbs, and corms are all modified stems, specialized for storage and vegetative propagation. Stolons are above-ground runners that root at their tips and form new plants. Rhizomes are horizontal underground stems that send up shoots. A bulb is a short stem surrounded by fleshy storage leaves, while a corm is a compact underground stem with stored reserves. A tuber is a swollen underground stem that stores nutrients and can sprout into a new plant (potatoes are a classic example). Because these structures originate as stems and primarily serve storage and asexual reproduction, they fall under specialized stems. They are not leaves, roots, or flowers.
