GeneralClass 12AllAnswered 27 Mar 2026
Answer
A cell is considered dead when its protoplasm ceases to function. Protoplasm (cytoplasm + nucleoplasm) is termed the "physical basis of life" because:
- It is the site of all metabolic activities
- Contains enzymes, genetic material, and organelles
- Maintains homeostasis and energy production
Death indicators:
- Loss of membrane integrity
- Cessation of metabolic reactions
- Inability to maintain ion gradients
- Nuclear fragmentation (karyorrhexis) or dissolution (karyolysis)
