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

To solve the question "Mark the odd one (w.r.t cytoskeleton)", we need to analyze the options provided in relation to the function and presence of the cytoskeleton in cells.

### Step-by-Step Solution:

1. **Understanding Cytoskeleton**:
- The cytoskeleton is a network of filaments and tubules that extends throughout the cytoplasm of eukaryotic cells. It plays a crucial role in maintaining the shape, internal organization, and mechanical support of the cell.

2. **Analyzing the Options**:
- **Option 1**: "Maintain shape of the bacterial cell"
- Bacterial cells are prokaryotic and do not have a cytoskeleton like eukaryotic cells. They maintain their shape through a rigid cell wall, not a cytoskeletal network.
- **Option 2**: "Network of the filamentous protein structure"
- This statement correctly describes the cytoskeleton, which is indeed made up of filamentous proteins.
- **Option 3**: "Provide mechanical support"
- This is a primary function of the cytoskeleton in eukaryotic cells, providing structural integrity and support.
- **Option 4**: "Regulate orientation and distribute the cell organelle"
- This is also a function of the cytoskeleton, as it helps in the positioning and movement of organelles within the cell.

3. **Identifying the Odd One Out**:
- Among the options, the first option "Maintain shape of the bacterial cell" is the odd one out because bacterial cells do not possess a cytoskeleton like eukaryotic cells do. Instead, they rely on their cell wall for shape maintenance.

### Conclusion:
The odd one out with respect to cytoskeleton is **"Maintain shape of the bacterial cell."**
