What organelle digests worn-out organelles and extracellular materials?

The organelle responsible for digesting worn-out organelles and extracellular materials is the lysosome. Lysosomes contain hydrolytic enzymes that break down macromolecules, old cell parts, and foreign substances. They play a crucial role in the cell's waste disposal system, ensuring that damaged or obsolete components are effectively recycled.

Lysosomes are involved in processes such as autophagy, where they digest defective organelles, maintaining cellular health and function. By breaking down complex substances into simpler molecules, lysosomes contribute to cellular homeostasis and help to prevent the accumulation of waste within the cell. This function is vital for overall cellular maintenance and contributes to the cell's ability to respond to environmental changes.
