(N/A) Role: Lysosomes act as the waste disposal system of the cell. They help in the digestion of foreign materials entering the cell,such as bacteria or food,and also remove worn-out cell organelles by digesting them.
Suicidal Bags: They are termed as 'suicidal bags' because when the cell gets damaged or its metabolic activity is disturbed,lysosomes may burst,and the digestive enzymes contained within them digest their own cell.
Mechanism: Lysosomes contain powerful digestive enzymes (hydrolytic enzymes) synthesized by the Rough Endoplasmic Reticulum $(RER)$. These enzymes are capable of breaking down all types of organic material,allowing the lysosome to digest unwanted cellular debris or foreign particles.
