Lysosomes are tiny sac like structures found in the cytoplasm. Each lysosome is surrounded by a single membrane and contains powerful enzymes. These enzymes are made by rough endoplasmic reticulum. Lysosomes are budded off from Golgi bodies.

Functions of lysosomes:

1. Lysosomes help in intracellular digestion.
2. They help to keep the cell clean by digesting any foreign material as well as worn-out cell organelles. That’s why they are called suicide bags, digestive bags or demolition squads.
