Some bacteria have a capsule outside cell wall , It is made of

Options

A. Protein
B. Cellulose
C. Fat
D. Mucopolysaccharide.

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Bacteria**: Bacteria have a cell wall that provides structure and protection. Some bacteria also have an additional layer called a capsule.

2. **Identifying the Capsule's Function**: The capsule serves several important functions, including providing virulence (which helps bacteria infect hosts) and protecting bacteria from environmental threats.

3. **Analyzing the Composition of the Capsule**: The question asks what the capsule is made of. We need to evaluate the given options:
- Option 1: Protein
- Option 2: Cellulose
- Option 3: Fat
- Option 4: Mucopolysaccharide

4. **Evaluating Each Option**:
- **Protein**: While proteins are important in many biological structures, they do not primarily make up the bacterial capsule.
- **Cellulose**: This is a carbohydrate found in plant cell walls, not in bacterial capsules.
- **Fat**: Fats are not a component of the bacterial capsule.
- **Mucopolysaccharide**: This is a type of polysaccharide that consists of long chains of sugar molecules and is indeed a major component of bacterial capsules.

5. **Conclusion**: Based on the analysis, the correct answer is that the capsule of some bacteria is made of **mucopolysaccharide**.

**Final Answer**: The capsule outside the cell wall of some bacteria is made of **mucopolysaccharide**.
