- 2. Type of cell that is made up of a nucleus, cell membrane and cytoplasm, but no cell wall.
- 3. wall A rigid structure in plant and fungal cells that gives them structure and support.
- 4. A specialised cell that has a tail so it can swim towards an egg cell.
- 5. A specialised cell that has long axons to carry electrical messages long distances.
- 7. Organelles that carry out cellular respiration to produce energy for the cell.
- 9. An organism that consists of a single cell.
- 12. The part of the cell which controls the activity of the cell.
- 13. The green pigment in chloroplasts.
- 16. The organelle that carries out photosynthesis in a plant cell.
- 17. A specialised cell that is biconcave in shape in order to carry more oxygen.

Down
- 1. cell A specialised plant cell for photosynthesis that contains many chloroplasts.
- 3. The 'skin' of the cell; it controls what substances can enter and exit the cell.
- 4. Cells that have specific structural adaptations to efficiently carry out a particular role in an organism.
- 6. A specialised cell that has a long thing projection to increase the surface area, allowing more water to be absorbed.
- 7. An organism that consists of many different cells working together.
- 8. Type of cell that contains a cell wall but no chloroplasts.
- 10. Single celled organisms such as Salmonella.
- 11. A specialised cell that has many mitochondria so that energy is continually available to the cell.
- 14. A single celled organism such as Euglena.
- 15. The jelly-like fluid inside the cell in which chemical reactions take place.
