Explanation:

• Ribosome: Synthesizes proteins, not involved in breaking down materials.
• Lysosome: Contains digestive enzymes to break down waste, foreign materials, and damaged organelles, acting as the cell's digestive system.
• Nucleus: Controls cell activities and stores genetic material, not a digestive structure.
• Endoplasmic Reticulum: Involved in protein and lipid synthesis/transport, not digestion.
