Select the mis-match

Options

A. Gas vacuoles- Green bacteria
B. Large central vacuole - Animal cell
C. Protists - Eukaryotes
D. Methanogens- Prokaryotes

Answer

To solve the question "Select the mismatch," we need to analyze each option provided and determine if the pair is correctly matched or not.

### Step-by-Step Solution:

1. **Analyze the First Option: Gas Vacuoles and Green Bacteria**
- Gas vacuoles are indeed found in cyanobacteria, which are a type of green bacteria.
- **Conclusion**: This pair is correctly matched.

2. **Analyze the Second Option: Large Central Vacuole and Animal Cell**
- Large central vacuoles are characteristic of plant cells, not animal cells. Animal cells typically have small vacuoles.
- **Conclusion**: This pair is mismatched.

3. **Analyze the Third Option: Protists and Eukaryotes**
- Protists are indeed classified as eukaryotes. They are a diverse group of organisms that have a defined nucleus.
- **Conclusion**: This pair is correctly matched.

4. **Analyze the Fourth Option: Methanogens and Prokaryotes**
- Methanogens are a type of archaea, which are indeed prokaryotic microorganisms that produce methane.
- **Conclusion**: This pair is correctly matched.

### Final Answer:
The mismatched pair is **Large Central Vacuole and Animal Cell** (Option 2).
