Mark the odd one (w.r.t cytoskeleton)

Options

A. Maintain shape of bacterial cell
B. Network of filamentous protein structure
C. Provide mechanical support
D. Regulate orientation and distribution of cell organelle

Answer

### Step-by-Step Solution:

1. **Understanding Cytoskeleton**:
- The cytoskeleton is a network of filamentous structures found in eukaryotic cells. It plays a crucial role in maintaining the shape and providing mechanical support to the cell.

2. **Identifying the Function**:
- The primary function of the cytoskeleton is to provide mechanical support to the cell. It is essential for maintaining the cell's shape and facilitating movement.

3. **Distinguishing Between Cell Types**:
- It is important to note that the cytoskeleton is not present in prokaryotic cells (such as bacteria). Prokaryotic cells have a different structural organization and do not have a cytoskeleton.

4. **Analyzing the Options**:
- When presented with options, we need to identify which one does not align with the characteristics of the cytoskeleton.
- The first option states "Maintain shape of bacterial cell." Since bacteria are prokaryotic cells and do not possess a cytoskeleton, this option is the odd one out.

5. **Conclusion**:
- Therefore, the odd one with respect to the cytoskeleton is "Maintain shape of bacterial cell," as it refers to a characteristic of prokaryotic cells, which do not have a cytoskeleton.
