Which of the following is not a characteristic feature of the animal cell membrane?
Correct answer: C. Prevents from osmotic lysis
- A. Maintains cellular homeostasis
- B. Regulates passage of molecules
- C. Prevents from osmotic lysis
Explanation
The correct answer is that the animal cell membrane does not prevent osmotic lysis. Animal cells lack a cell wall, which in plants provides additional protection against osmotic pressure. In hypotonic environments, water can freely enter animal cells, leading to swelling and potential bursting. The other options describe actual functions of the cell membrane: providing some mechanical support, maintaining homeostasis, and regulating molecule passage.
