- D
Composition and role
Lysosomes are named so due to their composition and role in the cell. Lysosomes are membrane bound organelles that contain digestive enzymes, such as proteases, nucleases, and lipases. They play a crucial role in intracellular digestion, breaking down various cellular components, foreign particles, and waste materials. The term "lyso" refers to their function of lysing or breaking down substances, while "somes" denotes their membranous structure. Hence, the name "lysosomes" accurately reflects their composition (enzymes) and their role (digestion and breakdown) in the cell. So, option D is selected.
Lysosomes are not named after their shape or size. They are named for their enzymatic function—“lyso” means to break or digest, and “some” means body—because they contain hydrolytic enzymes that digest cellular materials.
Shape and structure are variable (usually spherical or oval and membrane-bound) and are not the reason for their name.

Shape and structure are variable (usually spherical or oval and membrane-bound) and are not the reason for their name.
Lysosomes are named due to their content of hydrolytic enzymes that can break down (lyse) cellular materials—“lyso” means to break and “some” means body.
Structure: They are membrane-bound organelles, typically spherical, containing digestive enzymes and enclosed by a single lipid bilayer that protects the cell from self-digestion.
Role: Lysosomes perform intracellular digestion by breaking down food particles, cellular debris, and foreign substances. They also recycle worn-out organelles and participate in programmed cell death (apoptosis).
Lysosomes are named due to their role of hydrolytic enzymes that can lyse or digest cellular materials. The name “lysosome” comes from “lyso” (breakdown) and “some” (body).
