Select the odd one w.r.t functions of mesosome.

Options

A. Helps in respiration and secretion processes
B. Help in cell wall formation
C. Helps in formation of inclusion bodies
D. Helps in DNA replication

Answer

### Step-by-Step Solution:

1. **Understanding Mesosomes**:
- Mesosomes are invaginations of the plasma membrane found in bacteria. They play several important roles in bacterial cell functions.

2. **Identifying Functions of Mesosomes**:
- **Cellular Respiration**: Mesosomes contain respiratory enzymes that facilitate the process of respiration in bacteria.
- **Increasing Surface Area**: They help increase the surface area of the plasma membrane, which can enhance various cellular processes.
- **Cell Wall Formation**: Mesosomes are involved in the formation of the cell wall, particularly during cell division (mitosis).
- **Secretion of Enzymes**: They secrete enzymes that are essential for the electron transport chain, such as dehydrogenase.
- **DNA Replication**: Mesosomes assist in the distribution of chromosomes to daughter cells during cell division.

3. **Analyzing the Options**:
- The functions mentioned above are critical roles of mesosomes. We need to identify which option does not relate to these functions.
- The options include:
- Help in respiration (Correct)
- Help in secretion processes (Correct)
- Help in cell wall formation (Correct)
- Help in DNA replication (Correct)
- Help in the formation of inclusion bodies (Incorrect)

4. **Conclusion**:
- The odd one out is "help in the formation of inclusion bodies," as this is not a function associated with mesosomes.

### Final Answer:
The odd one with respect to functions of mesosomes is **"help in the formation of inclusion bodies."**
