Detailed explanation-1: -bilayer. noun. bi·lay·er ˈbī-ˌlā-ər, -ˌle(-ə)r. : a film or membrane with two molecular layers. a bilayer of phospholipid molecules.

Detailed explanation-2: -A Phospholipid Bilayer The cell membrane is composed mainly of phospholipids, which consist of fatty acids and alcohol. The phospholipids in the cell membrane are arranged in two layers, called a phospholipid bilayer.

Detailed explanation-3: -Phospholipids are made up of two layers, the outer and inner layers. The inside layer is made of hydrophobic fatty acid tails, while the outer layer is made up of hydrophilic polar heads that are pointed toward the water.

Detailed explanation-4: -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-5: -While one lipid bilayer. forms a single membrane, the double. membrane is composed of two parallel. lipid bilayers (Fig.
