Lysosomes are membrane-bound vesicular structures holding a variety of enzymes such as lipases, proteases, and carbohydrases. The purpose of lysosomes is to digest worn out cells. They are involved in the intracellular digestion of foreign food particles and microbes. Sometimes, they also act as suicidal bags. They are involved in the self digestion of cells. They are a kind of waste disposal systems of a cell. On the other hand, vacuoles are storage sacs found in cells. They might store the waste products of cells. In unicellular organisms, the food vacuole contains the consumed food particles. It also plays a role in expelling excess water and some wastes from the cell.
Lysosomes are membrane bound vesicular structures formed by the process of packaging in Golgi apparatus. The isolated lysosomal vesicles have been found to be very rich in almost all types of hydrolytic enzymes like lipases, proteases, carbohydrates etc. These enzymes are capable of digesting carbohydrates, proteins, lipids and nucleic acids.
Vacuoles are membrane bound space found in cytoplasm. It contains water, sap, excretory product and other unuseful products of cell. It is bound by a membrane called tonoplast which facilitates the transport of number of ions and other materials against concentration gradient into the vacuole.
