Answer:

C) the cell membrane forms a barrier that keeps all substances that might harm the cell from entering the cell .

Explanation:

The cells have a very thin "skin" that surrounds them, protects them from external factors and gives them individuality. It is the plasma membrane. Also known as plasmalema, it allows for a chemical composition inside the cell and a different one on the outside. This is essential for the performance of various functions in the body. The membrane also participates in the processes of recognition and communication between cells and allows the capture of signals from the so-called environment or extracellular environment.

It is true that the plasma membrane controls the exit and entry of substances into the cell, but unfortunately, it is not able to form a barrier that prevents all substances that can harm the cell from entering the cell.
