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

The question asked is about identifying which plant among the given options has a corm. To derive the correct solution, let's analyze and understand what a corm is and then examine each option:

A corm is a short, vertical, swollen underground plant stem that serves as a storage organ used by certain plants to survive adverse conditions. It is distinct from a bulb or rhizome.

• Garlic: Garlic is known to grow from a bulb, not a corm. Bulbs consist of layers, whereas corms do not have true layers.
• Arum / Colocasia: These plants are known to have corms. For example, Colocasia, commonly known as Taro, has a corm as its storage organ.
• Banana: Banana plants propagate using rhizomes, not corms. Rhizomes grow horizontally beneath the surface.
• Potato: A potato is a tuber, which is a swollen underground stem, but not a corm.

Based on this analysis, the correct answer is Arum / Colocasia, as these plants possess corms.
