Question

Which of the following plants has a corm?

• A. Garlic
• B. Arum / Colocasia
• C. Banana
• D. Potato

Hint:

To differentiate between storage organs, remember that corms are solid and rounded, while bulbs have multiple layers and tubers grow from a stem.

Answer 1

The Correct Option is B

A corm is a type of underground storage organ that is swollen, solid, and usually round in shape. It functions as a storage organ for energy, much like a bulb or tuber, but differs in structure. The corm is typical in plants like Arum and Colocasia (commonly known as taro), which store starches in their swollen base.
Garlic is a bulb, not a corm.
Bananas grow from a rhizome, which is different from a corm.
Potatoes are tubers, which are also distinct from corms.

Thus, the correct answer is Arum / Colocasia.
