Lysosomes are membrane bound vesicular structure, which contains all types of hydrolytic enzymes. The main function of these enzymes is the digestion of carbohydrates, proteins, lipids, and nucleic acids. Vacuoles are membrane bound space found in the cytoplasm, which contain water, sap, excretory products, and other materials not necessary for the cell. Its helps in the excretion of unwanted waste products. In some organisms like amoeba it forms food vacuole for digestion of food and also contractile vacuole for excretion of waste.
