Which organelle removes cell wastes and digests food with digestive enzymes in vesicles?

• A. Ribosomes
• B. Lysosomes
• C. Peroxisomes
• D. Golgi Bodies

Answer: (B)

Lysosomes are the cell’s waste-disposal and digestive units. They are membrane-bound sacs packed with digestive enzymes that work best in a small, acidic space. When the cell needs to recycle worn-out organelles or digest materials taken in by the cell, lysosomes fuse with those vesicles and dump their enzymes inside. The enzymes break down complex molecules into simpler ones the cell can reuse or excrete. This makes lysosomes essential for cleaning up cellular debris and providing the building blocks the cell needs.

Ribosomes aren’t involved in digestion; they build proteins. Peroxisomes help with detoxification and certain metabolic processes, not primarily digestion of wastes in vesicles. The Golgi apparatus packages and ships proteins and lipids, not digesting materials.
