- 3. A specialised cell that has many mitochondria so that energy is continually available to the cell.
- 5. Organelles that carry out cellular respiration to produce energy for the cell.
- 6. The jelly-like fluid inside the cell in which chemical reactions take place.
- 7. A specialised cell that has a long thing projection to increase the surface area, allowing more water to be absorbed.
- 8. The organelle that carries out photosynthesis in a plant cell.
- 10. A specialised cell that is biconcave in shape in order to carry more oxygen.
- 15. An organism that consists of a single cell.
- 17. The 'skin' of the cell; it controls what substances can enter and exit the cell.
- 19. In plants this organelle is very large and used to store water, sap and waste products.
- 20. The part of the cell which controls the activity of the cell.
