In potato, vegetative propagation takes place by

Options

A. leaves
B. stem
C. root
D. seeds

Answer

**Step-by-Step Solution:**

1. **Understanding Vegetative Propagation**:
- Vegetative propagation is a method of asexual reproduction in plants where new individuals are formed from the vegetative parts of the plant, such as stems, leaves, or roots, rather than from seeds.

2. **Identifying the Plant in Question**:
- The question specifically asks about potato plants. It is important to know the structure of the potato and how it reproduces.

3. **Recognizing the Modified Structure of Potato**:
- Potatoes are classified as modified stems known as tubers. These tubers have "eyes," which are nodes from which new plants can sprout.

4. **Evaluating the Options**:
- The options given are leaves, stem, root, and seed.
- Since we know that potatoes propagate through their tubers (modified stems), we can eliminate the other options:
- Leaves do not propagate potatoes.
- Roots can propagate some plants but not potatoes.
- Seeds are not the method of propagation for potatoes.

5. **Conclusion**:
- Based on the above reasoning, the correct answer is that vegetative propagation in potatoes takes place by **stem** (specifically, the tubers).

**Final Answer**: The correct option is **B) Stem**.
