Here's why:
* Lysosomes are the "recycling centers" of the cell. They contain powerful enzymes that break down various cellular components, including worn-out organelles, cellular debris, and even ingested pathogens like bacteria.
* Phagocytosis: When a cell encounters a bacterium, it can engulf it through a process called phagocytosis. This creates a membrane-bound vesicle containing the bacterium, which then fuses with a lysosome.
* Digestion: The lysosome's enzymes then break down the bacteria into smaller molecules that the cell can use or dispose of.
Note: Not all cells have the ability to engulf bacteria. This is a specialized function typically found in immune cells like macrophages and neutrophils.
