Which structure is the most important for cellular life?
Correct answer: B. Cell membrane
- A. Nucleus
- B. Cell membrane
- C. Chromosome
- D. Mitochondria
Explanation
The correct answer is the cell membrane, which is crucial for cellular life as it forms the outer boundary of the cell, providing structural support and regulating the movement of substances in and out of the cell. It ensures the cell maintains homeostasis, protecting its internal environment and allowing it to interact with its surroundings.
