Question: Lysosomes
Answer: A membrane-bounded organelle, found in the cytoplasm of eukaryotic cells, which contains digestive enzymes. It acts as the "garbage disposal" of the cell by breaking down cell components that are no longer needed as well as molecules or even bacteria that are ingested by the cell. The interior of a lysosome is strongly acidic, and its enzymes are active at an acid pH. Lysosomes are found in all eukaryotic cells, but are most numerous in disease-fighting cells, such as leukocytes (white blood cells).
