Options

A. banyan
B. maize
C. sweet potato
D. all of these

Answer

To solve the question, "In some plants like…………, roots arise from parts of the plant other than the part developed through radical," we need to identify plants that produce roots from parts other than the radical (the embryonic root).

### Step-by-Step Solution:

1. **Understanding Adventitious Roots**:
- Roots that develop from parts of the plant other than the radical are known as adventitious roots. These roots can arise from stems, leaves, or other non-root tissues.

2. **Identifying Examples of Plants with Adventitious Roots**:
- **Banyan Tree**: The banyan tree produces aerial roots from its branches that grow down into the soil, forming additional support.
- **Maize (Corn)**: In maize, roots can develop from the lower nodes of the stem, providing additional support and stability.
- **Sweet Potato**: Sweet potatoes develop storage roots that are also considered adventitious roots.
- **Sugarcane**: Similar to maize, sugarcane has supporting roots that arise from the stem.

3. **Evaluating the Options**:
- A. Banyan - Yes, it has adventitious roots.
- B. Maize - Yes, it has adventitious roots.
- C. Sweet Potato - Yes, it has adventitious roots.
- D. All of these - Since all the above plants exhibit the characteristic of having adventitious roots, this option is correct.

4. **Conclusion**:
- The correct answer is D. All of these. Each of the listed plants has roots that arise from parts other than the radical.

### Final Answer:
D. All of these
