Here's why:

* Intracellular digestion: Lysosomes are membrane-bound organelles that contain a variety of hydrolytic enzymes. These enzymes are capable of breaking down various cellular components, including:

* Worn-out organelles

* Cellular debris

* Engulfed bacteria or viruses

* Removal of parts and destruction of the whole: Lysosomes play a crucial role in the removal of damaged or unwanted cellular components. In some cases, lysosomal enzymes can even break down the entire cell, a process called autophagy.
