Ans:- The phospholipid bilayer of cell membrane consists of hydrophilic head and hydrophobic tail. hydrophilic head is polar and attract toward water whereas hydrophobic tail is made up of fatty acid which attract to each other. when lipid bilayer is in aqueous environment hydrophilic head attract toward water molecule and hydrophobic tail try to stay away from water and attract to fatty acid tail of other phospholipid therefore make lipid bilayer. because of hydrophilic and hydrophobic nature of phospholipid, it spontaneously arrange in lipid bilayer in aqueous environment.
