Which one of the following is a mismatched option of the cell with its feature given below

Options

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

Explanation

To solve the question regarding the mismatched option of the cell with its feature, we will analyze each option provided.

### Step-by-Step Solution:

1. **Identify the Options**:
We need to look at the options given in the question. The options typically relate to different types of cells and their corresponding features.

2. **Analyze Option 1: Gas Vacuoles in Green Bacterial Cells**:
- Gas vacuoles are present in certain bacteria, particularly those that perform photosynthesis, such as cyanobacteria.
- These vacuoles help the bacteria maintain buoyancy in aquatic environments, allowing them to float and absorb sunlight effectively.
- **Conclusion**: This option is correctly matched.

3. **Analyze Option 2: Large Central Vacuoles in Animal Cells**:
- In animal cells, vacuoles are generally small and numerous, not large.
- In contrast, plant cells have a large central vacuole that occupies a significant portion of the cell's volume.
- **Conclusion**: This option is mismatched, as it incorrectly states that large central vacuoles occur in animal cells.

4. **Analyze Option 3: Protists as Eukaryotes**:
- Protists are indeed eukaryotic organisms and can exhibit characteristics of both plants and animals.
- They serve as a connecting link between the two groups.
- **Conclusion**: This option is correctly matched.

5. **Analyze Option 4: Methanogens as Prokaryotes**:
- Methanogens are a type of archaea (prokaryotes) that produce methane and are found in anaerobic environments.
- They play a crucial role in the digestion of cellulose in ruminant animals.
- **Conclusion**: This option is correctly matched.

### Final Conclusion:
The only mismatched option is **Option 2**, which states that large central vacuoles occur in animal cells.
