Here's answer with explanation.

Explanation:

color(red)(Introducer)= Sc. Robertson

According to him, the cell membrane is made of a three layer sequence of protein-lipid-protein.

The external layer is a hydrophilic layer made of protein molecules of diameter 20A-25A. The middle layer is a light hydrophobic layer made of phospholipids of diameter 25A-35A.

The total breadth of the cell membrane is 65A-85A.
