Lysosomes are nicknamed 'suicide bags' because they
ADigest damaged organelles when the cell is injured
BCarry pigments that colour ripe fruits and petals
CStore starch grains for use during germination
DSynthesise proteins from amino acids on ribosomes
Answer & Solution
Correct answer: A. Digest damaged organelles when the cell is injured
1. Lysosomes contain about 40 digestive enzymes.
2. When the cell is old or injured, they rupture and release these enzymes.
3. The enzymes break down the cell's own organelles.
4. This self-digestion is why they are called suicide bags.
