The ____________determines the shape of the cell and provides a strong structural support to prevent the bacterium from bursting or collapsing :-

Options

A. Slime Layer only
B. Capsule only
C. Cell wall
D. Mesosome only

Answer

To answer the question, "The ____________ determines the shape of the cell and provides a strong structural support to prevent the bacterium from bursting or collapsing," we need to analyze the options provided and understand the functions of the structures mentioned.

### Step-by-Step Solution:

1. **Identify the Structures**: The options given are:
- Slime layer
- Capsule
- Cell wall
- Mesosome

2. **Understand the Functions**:
- **Slime Layer**: This is a loose layer of polysaccharides that can provide some protection but does not primarily determine the shape of the cell.
- **Capsule**: Similar to the slime layer, the capsule is a thicker layer that can protect bacteria but is not responsible for maintaining the cell's shape.
- **Cell Wall**: The cell wall is a rigid structure that surrounds the cell membrane in bacteria. It is primarily composed of peptidoglycan and is crucial for maintaining the shape of the cell and providing structural support. It prevents the bacterium from bursting or collapsing due to osmotic pressure.
- **Mesosome**: This is an infolding of the plasma membrane in bacteria and is involved in cell division and respiration, but it does not contribute to the shape or structural integrity of the cell.

3. **Choose the Correct Answer**: Based on the functions described, the cell wall is the structure that determines the shape of the cell and provides strong structural support. Therefore, the correct answer is:
- **Cell wall**

### Final Answer:
The **cell wall** determines the shape of the cell and provides a strong structural support to prevent the bacterium from bursting or collapsing.
