What is the primary function of lysosomes in a cell?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Digestion and removal of waste materials.
Lysosomes are membrane-bound organelles containing powerful hydrolytic enzymes capable of breaking down various biological molecules. They function as the cell's waste disposal system.
Their key activities include:
-
Digestion: Breaking down ingested material (through phagocytosis/endocytosis) and worn-out, damaged cell parts (a process called autophagy).
-
Waste Removal: Recycling unusable components and expelling cellular debris.
They are essential for maintaining cellular health and preventing the accumulation of toxic waste.
