Question
A corm differs from a bulb in that: a. Its stem is the main food storage organ b. It has flattened disc- shaped stem c. Buds are absent in the axils of the leaves d. Adventitious roots are present
Correct Answer
Option A is the correct answer.
Detailed Explanation
A corm (e.g., in gladiolus) is a swollen, underground stem base used for food storage. A bulb (e.g., in onion) is a structure with a short, flattened stem (disc) and fleshy, modified leaves (scales) that store food. So, in a corm, the stem itself is the main storage organ, whereas in a bulb, the leaves are.
Hint
Think about what part of the plant is swollen with food—the stem or the leaves?
