The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
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.
