Question

• What is the difference between apoptosis and necrosis?
• (b) What is the role of apoptosis in the normal, healthy development of animals?

Answer 1

• Apoptosis affects single cells while necrosis affects group of cells.
• Apoptosis includes no inflammation while necrosis does involve inflammatory processes.
• Apoptosis includes cell shrinkage while necrosis involves cell swelling.
• Apoptosis involves DNA condensation and non random dna fragmentation while necrosis involves random DNA fragmentation.

Apoptosis maintain normal development and growth by removing excess cells. It also removes mutant and damaged cells. It blocks replication of cells infected by virus.
