4. long term energy storage: Lipids are used for long - term energy storage. Match with b.
5. cholesterol: Cholesterol is a lipid. Match with b.
6. chains of fatty acids and glycerol: Lipids (triglycerides) are made of fatty acids and glycerol chains. Match with b.
7. plant cell walls: Plant cell walls have cellulose, a carbohydrate. Match with a.
