Animal Cells Lack Cell Walls and Chloroplasts

Steps:

• Identify key features of animal cells: no cell wall, no chloroplasts, have centrioles and lysosomes.
• Assume standard labeling: 1. centrioles, 2. cell wall, 3. lysosomes, 4. chloroplasts.
• Eliminate features unique to plants: cell wall (2) and chloroplasts (4) are absent in animal cells.
• Select pair with animal-specific features: 1 (centrioles) and 3 (lysosomes).

Why B is correct:

• Animal cells contain centrioles for cell division and lysosomes for digestion, per eukaryotic cell biology definitions.

Why the others are wrong:

• A includes cell wall, a plant feature.
• C includes cell wall and chloroplasts, both plant-specific.
• D includes only lysosomes and chloroplasts; chloroplasts are absent in animals.

Not enough information on exact feature labels, but based on standard biology.

Final answer: B
