Explanation:

1. Lipids are non - polar and insoluble in water.
2. Many lipids are composed of 1 molecule of glycerol and 3 fatty acid tails.
3. A carbohydrate composed of many sugar molecules is a polysaccharide.
4. Cellulose is the structural polysaccharide giving strength to plant cell walls.
5. A long, unbranched carbon - atom chain with a carboxyl group at one end is a fatty acid.
6. Glycogen is a carbohydrate, not a lipid.
7. Lipids are composed of C, H, O.
8. A lipid with 3 fatty acids joined to one glycerol is a triglyceride.
9. A fatty acid with at least one carbon - to - carbon double bond is unsaturated.
