Which feature is present in plant cells but not in animal cells?

• A. Nucleus
• B. Ribosomes
• C. Cell walls
• D. Mitochondria

Answer: (C)

Plants have a rigid cell wall made of cellulose that surrounds the cell membrane. This wall provides structural support, helps maintain shape, and protects the cell, while also enabling plant cells to withstand water pressure without bursting. Animal cells, on the other hand, do not have this rigid wall and rely on a flexible membrane and other structural components for support. The other features listed—nucleus, ribosomes, and mitochondria—are found in both plant and animal cells, so they don’t distinguish between the two. That makes the cell wall the feature unique to plant cells among these options.
