Question

Cell membrane is made up of a phospholipid bilayer with the phosphate group forming the head and the lipid chain forming the tail.

• A. True
• B. False

Answer 1

The correct option is A True

The phosphate group is the head in the bilayer and the lipid forms the tail. Chemically lipids don’t dissolve in water and hence give stability to the cell membrane against water. The phosphat group is hydrophillic and hence forms the outer and inner boundaries of the cell membrane with the lipid tails conjoined at the center, shielded from any water molecules.
