The correct Answer is:
To solve the question regarding the special membranous structure formed by the extensions of the plasma membrane into the cell, we can follow these steps: ### Step 1: Understand the Question The question asks for a specific structure that is formed by the extensions of the plasma membrane into the cell. We need to identify which of the given options fits this description. ### Step 2: Analyze the Options The options provided are: - Slime layer - Capsule - Mesosome - Plasmid ### Step 3: Evaluate Each Option 1. **Slime Layer**: This is a loose, protective layer outside the cell wall, but it is not an extension of the plasma membrane into the cell. 2. **Capsule**: Similar to the slime layer, the capsule is a protective layer but is not formed by the extensions of the plasma membrane. 3. **Mesosome**: This is an infolding of the plasma membrane found in prokaryotic cells. It is indeed formed by extensions of the plasma membrane into the cell. 4. **Plasmid**: This is a small, circular piece of DNA found in prokaryotes, but it is not a structure formed by the plasma membrane. ### Step 4: Identify the Correct Answer From the evaluation, the only option that correctly describes a structure formed by the extensions of the plasma membrane into the cell is **Mesosome**. ### Step 5: Conclusion Thus, the correct answer to the question is **Mesosome**. ---
