Concept:Lysosomes are membrane-bound organelles that contain digestive enzymes. Their main job is to break down waste and foreign materials inside the cell.Explanation:Lysosomes carry out intracellular digestion by breaking down proteins, lipids, carbohydrates, and nucleic acids into simpler molecules. These molecules can then be reused or removed. This process is often called the cell’s “garbage disposal system.” Lysosomes also help in autophagy, where damaged organelles are digested to maintain cell health. They play a role in immune defense by breaking down pathogens taken in by cells like macrophages. Additionally, lysosomes are involved in programmed cell death (apoptosis) and repair of the plasma membrane. They do not store genetic material, produce energy, or form proteins—those functions belong to the nucleus, mitochondria, and ribosomes, respectively.Answer:C. Carry out intracellular digestion
