Explanation:

1. Organic compounds contain carbon - carbon bonds.
2. Carbon has 4 valence electrons.
3. Carbon can form straight chains, branched chains, and rings with other carbon atoms.
4. Clusters of atoms attached to carbon skeletons are functional groups.
5. -PO₄ is a phosphate group.
6. -OH is a hydroxyl group.
7. -NH₂ or -NH₃⁺ is an amino group.
8. -COOH is a carboxyl group.
9. A very large organic molecule composed of many atoms is a macromolecule.
10. The process of building large molecules from small ones is polymerization.
11. A simple molecule that can combine to form a larger molecule is a monomer.
