Options

A. Cucumber
B. Dioscorea
C. Agave
D. Grapevine

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which plant utilizes modified axillary buds to assist in climbing. Modified axillary buds can develop into structures that help plants attach to supports.

2. **Identifying Key Terms**: The key term here is "modified axillary buds." These are typically transformed into tendrils, which are specialized structures that aid in climbing.

3. **Analyzing the Options**:
- **Option A: Cucumber**: Cucumber plants have tendrils that are modified axillary buds, which help them climb.
- **Option B: Dioscoria**: This plant is known for its tubers but does not primarily use modified axillary buds for climbing.
- **Option C: Agave**: Agave plants are typically rosette-forming and do not climb; they do not utilize tendrils.
- **Option D: Grapevine**: Grapevines also have tendrils that help them climb, but the question specifically asks for the best example.

4. **Determining the Correct Answer**: While both cucumber and grapevine have climbing abilities through tendrils, the question specifically asks for modified axillary buds, which are most characteristically associated with cucumbers.

5. **Conclusion**: The correct answer is **Option A: Cucumber**, as it is a clear example of a plant that uses modified axillary buds in the form of tendrils to climb.
