In Class 9 Biology (The Fundamental Unit of Life), every cell organelle has a specific nickname based on its job (like Mitochondria is the Powerhouse). A very frequent exam question asks about the 'Suicide Bags' of the cell.
Organelle: Lysosome.
Enzymes: Contains powerful hydrolytic (digestive) enzymes made by the Rough Endoplasmic Reticulum (RER).
Function: Waste disposal and cellular self-destruction (Autolysis).
The Lysosomes are known as the suicide bags of the cell.
Lysosomes usually act as the 'garbage disposal' system of the cell. They digest foreign materials (like dangerous bacteria) and eat up old, worn-out cell parts to keep the cell clean.
However, when the cell gets severely damaged or infected, the cellular metabolism breaks down. In such a critical situation:
Because the lysosome sacrifices and kills its own cell to prevent an infection from spreading to other healthy cells, it is famously called the 'Suicide Bag'.
Lysosomes contain highly powerful digestive enzymes. If a cell gets severely damaged or infected, the lysosome bursts open and its enzymes completely digest and destroy its own cell. Therefore, they are called the suicide bags of the cell.
