Concept:Lysosomes are membrane-bound organelles that contain digestive enzymes for breaking down cellular waste and foreign materials.
Explanation:Lysosomes are vesicular structures formed by the Golgi apparatus.
They are rich in hydrolytic enzymes like lipases, proteases, and carbohydrases, which function optimally at acidic pH.
These enzymes digest carbohydrates, proteins, lipids, and nucleic acids.
Other organelles listed do not store digestive enzymes:
• Mitochondria produce energy (powerhouse of the cell).
• Vacuoles store water, sap, and waste, not digestive enzymes.
• Ribosomes manufacture proteins but do not contain digestive enzymes.
Answer:Lysosomes
