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.

The statement is not correct regarding the functioning of the cell membrane of all organisms is:

  • The cell membrane forms a barrier that keeps all substances that might harm the cell from entering the cell.

What is cell membrane?

It is a double layer of phospholipids that allows desired substances to enter the cell and deny entry to unwanted ones, serving as communication between the outside and the inside.

Characteristics of cell membrane

  • It is the wall that cells have allowing them to remain independent from the external environment.

  • It allows or rejects the entry of certain molecules into the cell, but it cannot control the entry of all substances that might harm the cell.

  • It mechanically defines and protects the cell, distinguishing the outside from the inside, and one cell from another.

Therefore, we can conclude that among the functions of the cell membrane is transport, recognition and communication, allowing interaction with the outside.
