Which type of asexual reproduction is observed in Hydra ?

Options

A. Exogenous budding
B. Endogenous budding
C. Gemmule formation
D. Both (1) & (3)

Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question asks about the type of asexual reproduction in Hydra. Hydra is a small, freshwater organism belonging to the phylum Cnidaria.

2. **Understand Asexual Reproduction**: Asexual reproduction involves a single parent and results in offspring that are genetically identical to the parent. This means there is no fusion of gametes.

3. **Types of Asexual Reproduction**: There are several types of asexual reproduction, including binary fission, fragmentation, spore formation, and budding.

4. **Focus on Budding**: In Hydra, the primary mode of asexual reproduction is budding. This process involves the formation of a new individual (bud) from the body of the parent organism.

5. **Differentiate Between Types of Budding**: Budding can be classified into two types:
- **Exogenous Budding**: Buds form on the outer surface of the parent organism.
- **Endogenous Budding**: Buds form internally.

6. **Confirm the Type in Hydra**: In Hydra, the budding occurs externally, meaning it is classified as exogenous budding. The bud develops on the outer surface of the parent Hydra and eventually detaches to become an independent organism.

7. **Conclusion**: Therefore, the type of asexual reproduction observed in Hydra is exogenous budding.

**Final Answer**: Exogenous budding.
