Damage to one of the following immediately kills the cell whether its prokaryotic or eukaryotic?
Correct answer: B. Cell membrane
- A. Nucleus
- B. Cell membrane
- C. Mitochondria
- D. All of these
Explanation
The cell membrane is essential for maintaining the cell's internal environment by regulating the passage of substances in and out of the cell. Damage to this structure leads to the uncontrolled loss of cell contents, resulting in immediate cell death. While the nucleus and mitochondria are crucial for cell functions, their damage does not result in instant cell death, as the cell can maintain short-term viability through other mechanisms.
