Which of the following statements is true about the structure of the cell membrane?

the two layers of the plasma membrane are identical.
the plasma membrane is a rigid structure.
the proteins on the two layers are not identical.
proteins are found only on one surface of the membrane.

The correct answer is:

The two layers of the plasma membrane are identical.

Explanation:

The plasma membrane is called a lipid bilayer because it is composed of two layers of cells and it makes the boundary of cell.

The other three statements are false because

Plasma membrane is semipermeable i.e it allows the transport of materials inside and outside the cell.

The proteins in the plasma membrane are integral proteins

The proteins in the plasma membrane are extensively folded and protruding from the membrane are in contact with inside and outside the cell.
