Stem is reduced in

Options

A. Rhizome
B. Corm
C. Bulb
D. Tuber

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which structure has a reduced stem. We need to analyze the options provided: rhizome, corm, bulb, and tuber.

2. **Analyzing the Options**:
- **Rhizome**: A rhizome is a type of stem that grows horizontally underground. It is not reduced; instead, it is a modified stem that serves as a storage organ and a means of vegetative reproduction.

- **Corm**: A corm is a swollen underground stem that serves as a storage organ. While it is a modified stem, it is not considered a reduced stem.

- **Bulb**: A bulb is a short stem that is significantly reduced and surrounded by fleshy leaves or leaf bases. It serves as a storage organ for nutrients, allowing the plant to survive adverse conditions. The stem is very much reduced in a bulb, making this option a strong candidate.

- **Tuber**: A tuber is a thickened underground part of a stem that stores nutrients. While it is a modified stem, it is not reduced in the same way as a bulb.

3. **Identifying the Correct Answer**: Based on the analysis, the bulb is the structure where the stem is extremely reduced. Therefore, the correct answer to the question is **bulb**.

4. **Conclusion**: The correct option for the question "Stem is reduced in" is **bulb**.
