Explanation:

1. Lipids are non - polar and insoluble in water.
2. 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 very long, unbranched chain of carbon atoms with a carboxyl group at one end is a fatty acid.
6. Glycogen is a carbohydrate, not a lipid.
