Which organelle in animal cells can digest foreign materials?

Correct option is B

The correct answer is (b) Lysosome. Lysosomes are membrane-bound organelles in animal cells that contain digestive enzymes. These enzymes can break down various biomolecules, including proteins, lipids, and carbohydrates. Lysosomes play a critical role in the immune response by digesting foreign materials such as bacteria and viruses that enter the cell. They also break down damaged or worn-out cell components in a process called autophagy, maintaining cellular health.
Information Booster: ● Lysosomes are often referred to as the "suicide bags" of the cell due to their ability to digest cellular components. ● They contain hydrolytic enzymes that are capable of breaking down many types of biological substances. ● Lysosomes are involved in processes like phagocytosis (engulfing and digesting pathogens) and autophagy (digesting damaged organelles). ● They maintain an acidic environment (pH around 4.5-5) optimal for their digestive enzymes. ● Defects in lysosomal enzymes can lead to diseases such as Tay-Sachs and Gaucher’s disease, which are types of lysosomal storage disorders. ● Lysosomes are more abundant in cells involved in immune responses, such as macrophages.
