The _____________ removes toxic waste from cells so that it can be excreted from the body of animals.

• A. Vesticles
• B. Lysosomes
• C. Mitochondria
• D. Nuclei

Answer: (A)

Lysosomes act as the cell’s recycling and cleaning crew, housing enzymes that digest waste materials, damaged organelles, and toxic substances inside the cell. By breaking these wastes down into smaller, reusable or excretable pieces, lysosomes help keep the cellular environment safe. Once digestion happens, the resulting materials can be moved in vesicles to the cell membrane for exocytosis, allowing waste to leave the body. Mitochondria are the energy factories, nuclei store genetic material, and vesicles are transport carriers that move substances around the cell but don’t perform digestion themselves. Because of their digestive role, lysosomes are the organelles most closely associated with removing toxic waste from cells.
