Question

What is not a function of the cell membrane –

a) to provide shape to the cell

b) to keep all the cellular contents safe from surrounding environment

c) to allow all materials to move in and out of the cell

d) all are functions of the cell membrane​

Answer 1

The correct option is D;

• All are the functions of the cell membrane​.

• You know that a cell membrane is a biological membrane, also known as a plasma membrane, that protects the cell from the outer environment.

• The cell membrane provides shape to the cell.

• Cell membranes keep all the cellular contents safe from the outer environment

• It allows all the materials to move in and out of the cell. So it is called a semipermeable membrane.
• Hence all are the functions of the cell membrane​.

Answer 2

All are functions of the cell membrane.

Explanation:

• The cell membrane is also known as the plasma membrane which separates the interior of the cell from the external environment and is found in all cells.

• A semi-permeable lipid bilayer makes up the cell membrane. The transit of chemicals into and out of cells is regulated by cell membranes.

• They keep toxins away from cells.
