Explanation:
Detailed explanation-1: -The cell membrane consists of a double layer of lipid molecules covered by two layers of proteins.
Detailed explanation-2: -When cellular membranes form, phospholipids assemble into two layers because of these hydrophilic and hydrophobic properties. The phosphate heads in each layer face the aqueous or watery environment on either side, and the tails hide away from the water between the layers of heads, because they are hydrophobic.
Detailed explanation-3: -Membranes consist largely of a lipid bilayer, which is a double layer of phospholipid, cholesterol, and glycolipid molecules that contains chains of fatty acids and determines whether a membrane is formed into long flat sheets or round vesicles.
