Show answer and explanation
Correct answer: (A) P-1, Q-2, R-3, S-4
Explanation
Match each cell component with its function.
- **P. Lysosome:** contains hydrolytic enzymes that **digest macromolecules**. P-1.
- **Q. Peroxisome:** contains catalase and oxidases that **detoxify harmful compounds** such as hydrogen peroxide. Q-2.
- **R. Glyoxysome:** a plant peroxisome that runs the glyoxylate cycle, **converting stored fatty acids to sugar** in germinating seeds. R-3.
- **S. Cytoskeleton:** microtubules, actin and intermediate filaments give shape and enable **cell motility**. S-4.
Match: **P-1, Q-2, R-3, S-4** (option A).
