Asexual reproductive structure of Hydra is :

Options

A. Gemmule
B. Bud
C. Conidia
D. None of these

Answer

### Step-by-Step Solution:

1. **Understanding Asexual Reproduction**:
- Asexual reproduction involves a single parent organism producing offspring without the fusion of gametes. The offspring are genetically and morphologically identical to the parent, referred to as clones.

2. **Identifying Asexual Reproductive Structures**:
- Common asexual reproductive structures include:
- Zoospores
- Buds
- Gemmules
- Conidia

3. **Evaluating the Options**:
- **Gemmules**: These are reproductive structures found in sponges, not in Hydra. Therefore, this option is incorrect.
- **Buds**: In Hydra, asexual reproduction occurs through a process called budding, where a small outgrowth (bud) forms on the parent organism.
- **Conidia**: This structure is associated with fungi and is not relevant to Hydra. Thus, this option is also incorrect.

4. **Understanding the Budding Process**:
- In Hydra, a bud forms as an outgrowth from the parent. Initially, the bud is attached to the parent but eventually detaches to become a new individual.

5. **Conclusion**:
- The correct answer to the question "Asexual reproductive structure of Hydra is:" is **Buds**.
