Detailed explanation-1: -Phospholipid molecules are a type of lipid that bears a head and two tails. The Head comprises a phosphate group which makes it polar and water-loving or hydrophilic. Two tails of phospholipids are nonpolar and hydrophobic as it comes from fatty acids.

Detailed explanation-2: -The plasma membrane is composed mainly of phospholipids, which consist of fatty acids and alcohol. The phospholipids in the plasma membrane are arranged in two layers, called aphospholipid bilayer. As shown in Figure below, each phospholipid molecule has a head and two tails.

Detailed explanation-3: -1: A phospholipid consists of a head and a tail. The “head” of the molecule contains the phosphate group and is hydrophilic, meaning that it will dissolve in water. The “tail” of the molecule is made up of two fatty acids, which are hydrophobic and do not dissolve in water.

Detailed explanation-4: -Each phospholipid molecule has a head and two tails. The head “loves” water (hydrophilic) and the tails “hate” water (hydrophobic). The water-hating tails are on the interior of the membrane, whereas the water-loving heads point outwards, toward either the cytoplasm or the fluid that surrounds the cell.

Detailed explanation-5: -Each phospholipid is amphipathic, with two hydrophobic tails and a hydrophilic head. The hydrophobic tails face inward towards one another, and the hydrophilic heads face outwards.
