  • Lysosomes are the cell organelles found in the eukaryotic cells. They are used for the degradation of macromolecules by the process of phagocytosis, endocytosis, and autophagy.
  • They digest (breakdown) macromolecules (carbohydrates, lipids, proteins, and nucleic acids), repair cell membranes and respond against foreign substances such as bacteria, viruses, and other antigens.
  • They digest the macromolecules with the help of the digestive enzymes that break down the macromolecules and foreign invaders.
  • Due to the phagocytic nature, they are also called heterophonic vacuole or phagolysosome.
  • So, the correct answer is option A.
