Final answer:
Lysosomes are organelles containing digestive enzymes that break down various particles.
Step-by-step explanation:
Lysosomes are organelles that contain digestive enzymes which break down various particles. They are membrane-bound organelles of the endomembrane system. Lysosomes play a crucial role in cellular digestion, breaking down substances such as food, damaged organelles, cellular debris, microorganisms, or immune complexes. They compartmentalize the digestive enzymes, allowing them to efficiently digest matter without harming the rest of the cell.
