1. The energy-releasing organelle, often called the "powerhouse" of the cell.
3. The central organelle that contains the cell's genetic material (DNA).
5. The main component of the cell membrane; also used for long-term energy storage.
7. The type of teeth with a sharp, pointed shape, used for tearing food.
9. The tough, protective outer layer of a tooth, the hardest substance in the human body.
11. The type of teeth with a large, flat surface for crushing and grinding food.
12. A biological molecule made of amino acids, essential for growth and repair.
13. The smallest biological unit of a living organism.
14. A biological molecule like glucose, used by cells for immediate energy.

2. The type of teeth at the front of the mouth, shaped for cutting and biting.
4. A large specialised cell designed to carry genetic material to the female gamete.
6. The layer of living tissue under the enamel and dentine, containing nerves and blood vessels.
