The correct answer is A) its stem is the main food storage organ.
A corn, also known as a corm, is a type of underground stem that serves as a food storage organ. It is a swollen, solid stem that stores nutrients and water, allowing the plant to survive during periods of drought or cold weather. Examples of plants that produce corms include gladiolus and crocus.
In contrast, a bulb is a type of underground storage organ that consists of layered, fleshy leaves that store food and water. Examples of plants that produce bulbs include onions, garlic, and tulips.
The other options are not correct:
B) A corn does not have a flattened, disc-shaped stem.
C) Buds are actually present in the axils of the leaves in a corn, and these buds can produce new shoots and roots.
D) Adventitious roots are present in both corms and bulbs, and are not a distinguishing feature between the two.
