The correct Answer is:
To solve the question regarding the functions of mesosomes, we need to analyze each of the provided options and determine which one is not a function of mesosomes. ### Step-by-Step Solution: 1. **Understanding Mesosomes**: - Mesosomes are membrane-bound structures found in prokaryotic cells, particularly in bacteria. They are formed by the invagination (folding in) of the plasma membrane into the cytoplasm. 2. **Evaluating the Functions of Mesosomes**: - Mesosomes are known to assist in several cellular processes. Let's evaluate each option provided in the question. 3. **Option 1: Cell Wall Formation**: - Mesosomes play a role in the formation of the cell wall. They help in synthesizing the components required for the cell wall. Thus, this option is a function of mesosomes. 4. **Option 2: DNA Replication**: - Mesosomes are also involved in DNA replication. They help in the segregation of the replicated DNA during cell division. Therefore, this option is also a function of mesosomes. 5. **Option 3: Polysome Formation**: - Polysomes are clusters of ribosomes that are engaged in protein synthesis. Mesosomes do not participate in the formation of polysomes. This is the option that does not represent a function of mesosomes. 6. **Option 4: Secretion Process**: - Mesosomes are involved in the secretion process, as they contain various enzymes that assist in cellular respiration and other secretory functions. Thus, this option is also a function of mesosomes. 7. **Conclusion**: - After evaluating all the options, the only function that is not associated with mesosomes is **polysome formation**. ### Final Answer: The correct answer is **polysome formation**. ---
