Lysosomes are membrane-bound organelles found in animal cells containing hydrolytic enzymes. These enzymes are capable of breaking down various biological molecules, including waste materials, cellular debris, and foreign particles (like bacteria or viruses) that are taken into the cell through processes like phagocytosis. This digestive function helps in cellular waste removal, recycling, and defense against pathogens.

– Lysosomes contain powerful digestive enzymes.
– They are involved in phagocytosis (digestion of foreign particles) and autophagy (digestion of cellular components).

The Endoplasmic Reticulum is involved in protein and lipid synthesis. Golgi apparatus modifies, sorts, and packages proteins and lipids. Mitochondria are responsible for cellular respiration and energy production. None of these organelles primarily function in digesting foreign materials within the cell.
