Each lysosome consists of mainly two parts: a limiting membrane and an inner dense mass or matrix. This is a single-unit membrane on the outside of the lysosome and is composed of lipoproteins. Lysosomes Definition Lysosomes definition: Lysosomes are membrane-bound cell organelles containing digestive enzymes that break down macromolecules, cellular debris, and foreign invaders within eukaryotic cells. Structure and Diagram of Lysosomes A typical lysosome is a spherical sac surrounded by a single membrane. Lysosomes are membrane-bound, dense granular structures containing hydrolytic enzymes responsible mainly for intracellular and extracellular digestion. The word “lysosome” is made up of two words “lysis” meaning breakdown and “soma” meaning body. Diagram of lysosomes: Lysosomes are the cell's degradation compartments and are primarily involved in the digestion of proteins, DNA, RNA,
