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 solve the question of which plant has a stem that performs the function of storage and perennation, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Functions of Plant Parts**:
- Recognize that different parts of plants (roots, stems, leaves) can have specialized functions.
- Storage of food and perennation (survival through unfavorable conditions) can occur in different plant parts.

2. **Identify the Options**:
- The question provides several plant options. We need to analyze each one to determine where the storage function occurs.

3. **Analyze Each Plant**:
- **Radish**: In radish, the roots are modified for storage. Therefore, the stem does not perform this function.
- **Wheat**: In wheat, the seeds are the storage organs. The stem does not store food.
- **Groundnut**: In groundnut, the seeds are responsible for storage. Again, the stem does not play this role.
- **Ginger**: In ginger, the stem (specifically, the rhizome) is modified for storage. It stores food and helps the plant survive unfavorable conditions.

4. **Conclusion**:
- Based on the analysis, the correct answer is **ginger** because it is the only plant listed where the stem performs the function of storage and perennation.

### Final Answer:
The plant in which the stem performs the function of storage and perennation is **ginger**.
