In which of the following plants does the stem perform the function of storage and perennation?

Options

A. Radish
B. Wheat
C. Ginger
D. Groundnut

Answer

To determine which plant has a stem that performs the functions of storage and perennation, we can analyze each option provided.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are Radish, Wheat, Ginger, and Groundnut.

2. **Analyze Radish**:
- Radish is known for its storage roots.
- Since the question specifically asks about storage in stems, Radish is **not** the correct answer.

3. **Analyze Wheat**:
- Wheat does not have significant stem or root modifications for storage or perennation.
- Therefore, Wheat is also **not** the correct answer.

4. **Analyze Ginger**:
- Ginger is an example of an underground stem modification known as a rhizome.
- Rhizomes grow horizontally beneath the soil and serve the functions of storage (storing nutrients) and perennation (surviving adverse conditions).
- Thus, Ginger is a **correct answer**.

5. **Analyze Groundnut**:
- Groundnut (or peanut) does not have a stem that serves the function of storage or perennation in the same way as rhizomes do.
- Hence, Groundnut is **not** the correct answer.

6. **Conclusion**:
- After analyzing all options, the plant in which the stem performs the functions of storage and perennation is **Ginger**.

### Final Answer:
The correct answer is **Ginger**.
