What provides an additional layer of protection around the membrane of a cell?

Cell wall
Chloroplast
Lysosome
Vacuole

The correct answer is: Cell wall

The cell wall provides an additional layer of protection around the cell membrane, particularly in plant cells, fungi, and some bacteria. It is composed primarily of cellulose in plants, which gives structure and rigidity, allowing the cell to maintain its shape while also protecting it from physical damage and harmful pathogens. In contrast, the other structures listed, such as chloroplasts, lysosomes, and vacuoles, serve different functions within the cell, including photosynthesis, digestion, and storage, but they do not contribute an extra protective layer around the cell membrane. Thus, the cell wall stands out as the correct answer for providing additional structural support and protection.
