In this article, we will study the structure and function of lysosomes with the help of a lysosome diagram. The diagram of the lysosome shows an outer membrane embedded with numerous transport proteins and is filled with enzymes. Lysosomes – Definition, Diagram, Structure and Functions Lysosomes are cell organelles that break down waste, worn-out cell parts, and foreign invaders, helping maintain cellular cleanliness. Other details about lysosome and its structure are discussed here 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. Diagram of lysosomes: Lysosomes are the cell's degradation compartments and are primarily involved in the digestion of proteins, DNA, RNA,
