What is the function of lysosomes?

  1. Transport cellular material

  2. Produce energy

  3. Break down cellular material

  4. Produce proteins

The correct answer is: Break down cellular material

Lysosomes are organelles found within cells that contain enzymes important for digesting or breaking down various types of materials, such as worn out cell parts, food particles, or even invading foreign substances. The enzymes within lysosomes help to break down these materials into simpler components that can then be used by the cell. Option A is incorrect because transport of cellular material generally takes place through the Golgi body or cell membrane. Option B is incorrect because the organelle responsible for producing energy is the mitochondria. Option D is incorrect because protein production occurs in the ribosomes and endoplasmic reticulum.
