What is the function of the cell membrane? A. contains DNA B. determine what gets in and out of the nucleus C. makes proteins D. packages proteins
The function of the cell membrane is primarily to regulate what enters and exits the cell, providing a barrier that controls the movement of substances in and out. Therefore, the correct answer is:
None of the options directly describe the function of the cell membrane.
However, if we were to choose the closest option related to cellular functions, it would be:
B. determine what gets in and out of the nucleus (though this specifically refers to the nuclear membrane, the cell membrane also plays a role in regulating the movement of substances in and out of the cell).
