Which of the following organisms reproduces by binary fission ?

Options

A. Hydra
B. Yeast
C. Amoeba
D. Sea anemone

Answer

**Step-by-Step Solution:**

1. **Understand Binary Fission**: Binary fission is a type of asexual reproduction where a single parent organism divides into two identical daughter cells. This process is common in unicellular organisms.

2. **Identify the Characteristics of Binary Fission**: In binary fission, the parent cell duplicates its genetic material and then divides into two equal parts. This means that only one parent is involved in the reproduction, making it uniparental.

3. **Review the Given Options**: The organisms listed in the question are:
- Hydra
- Yeast
- Amoeba
- Anemone

4. **Analyze Each Organism**:
- **Hydra**: This organism reproduces primarily through budding, not binary fission.
- **Yeast**: Yeast reproduces by a process called budding, which is also a form of asexual reproduction but not binary fission.
- **Amoeba**: This is a unicellular organism that reproduces by binary fission. It divides into two daughter cells, making it a suitable example of binary fission.
- **Anemone**: Anemones are multicellular organisms that reproduce sexually or through a process called fragmentation, not binary fission.

5. **Select the Correct Answer**: Based on the analysis, the organism that reproduces by binary fission is **Amoeba**.

6. **Conclusion**: Therefore, the correct answer to the question is **Amoeba**.
