Understand the function of each organelle listed in the problem: Golgi apparatus, lysosomes, mitochondria, and ribosomes.
Recall that lysosomes are membrane-bound organelles that contain digestive enzymes.
These enzymes in lysosomes are responsible for breaking down macromolecules, old cell parts, and microorganisms.
Compare this function with the other organelles: Golgi apparatus is involved in modifying, sorting, and packaging proteins; mitochondria are the powerhouses of the cell, generating ATP; ribosomes are the sites of protein synthesis.
Conclude that lysosomes are the organelles that contain enzymes specifically for breaking down old cell parts.
