Below are the steps of digestion and removal of wastes through lysosomes:

• The primary lysosome is generated by the Golgi.
• The primary lysosome fuses with a phagosome and forms secondary lysosome.
• Digestive vacuoles are formed in which digestion of food materials takes place. Small molecules generated by digestion diffuse into the cytoplasm.
• Residual bodies are formed in which the undigested materials are collected. These bodies then fuse with the plasma membrane to release the undigested waste materials.
