Lysosome vs. Vacuole — What's the Difference?
Lysosomes are membrane-bound organelles containing enzymes that break down waste materials and cellular debris. Vacuoles are also membrane-bound but mainly serve as storage units for nutrients, waste, and other substances.
Difference Between Lysosome and Vacuole
Table of Contents
Lysosomes are specialized vesicles within cells that contain enzymes for breaking down waste and foreign material. Vacuoles, on the other hand, are more generalized compartments that store a variety of substances including nutrients and waste products.
Both lysosomes and vacuoles are membrane-bound organelles but differ significantly in function. While lysosomes act as the cell's "recycling center," vacuoles are more like "storage bins."
In animal cells, lysosomes are generally more prominent and have a more specialized function compared to vacuoles. In plant cells, however, vacuoles are larger and more prominent, serving roles in turgor pressure and waste storage.
Lysosomes are created by the Golgi apparatus and are rich in enzymes that catalyze the breakdown of cellular waste. Vacuoles do not have such a specialized origin and can be created through various cellular mechanisms.
Enzymes within lysosomes function best at acidic pH levels, maintained by proton pumps in the lysosomal membrane. Vacuoles in plant cells may also maintain acidity but are not specialized for enzyme activity.

A lysosome () is a membrane-bound organelle found in many animal cells. They are spherical vesicles that contain hydrolytic enzymes that can break down many kinds of biomolecules.
A vacuole () is a membrane-bound organelle which is present in plant and fungal cells and some protist, animal, and bacterial cells. Vacuoles are essentially enclosed compartments which are filled with water containing inorganic and organic molecules including enzymes in solution, though in certain cases they may contain solids which have been engulfed.
A membrane-bound organelle in the cytoplasm of most cells containing various hydrolytic enzymes that function in intracellular digestion.
A membrane-bound organelle in the cytoplasm of most cells, especially plant cells, containing water and dissolved substances such as salts, sugars, enzymes, and amino acids.
(cytology) An organelle found in all types of animal cells which contains a large range of digestive enzymes capable of splitting most biological macromolecules.
A small extracellular cavity or space within tissues.
An organelle found in the cytoplasm of most cells (especially in leukocytes and liver and kidney cells)
(cytology) A large membrane-bound vesicle in a cell's cytoplasm.
A small empty or air-filled space or vacuity.
A small air cell, or globular space, in the interior of organic cells, either containing air, or a pellucid watery liquid, or some special chemical secretions of the cell protoplasm.
A tiny cavity filled with fluid in the cytoplasm of a cell
