Which organelle contains enzymes that digest damaged organelles and waste?

Explanation:
Lysosomes are the organelles that contain digestive enzymes. They act as the cell’s recycling centers, using hydrolytic enzymes that work best in an acidic interior to break down damaged organelles and waste material brought into the cell. This process, autophagy for damaged pieces and endocytosis for external material, helps recycle components and maintain cellular health. Peroxisomes mainly detoxify chemicals and break down fatty acids, vacuoles store water and nutrients and can contain some enzymes in plant cells but aren’t the primary organelle for digesting damaged organelles, and ribosomes build proteins rather than digest them.
