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

  1. 1. Type of cell that contains a cell wall but no chloroplasts.
  2. 2. Type of cell that is made up of a nucleus, cell membrane and cytoplasm, but no cell wall.
  3. 4. The green pigment in chloroplasts.
  4. 5. An organism that consists of many different cells working together.
  5. 6. wall A rigid structure in plant and fungal cells that gives them structure and support.
  6. 9. A single celled organism such as Euglena.
  7. 11. A specialised cell that has a tail so it can swim towards an egg cell.
  8. 12. Type of cell that contains chloroplasts and a cell wall made of cellulose.
  9. 13. cell A specialised plant cell for photosynthesis that contains many chloroplasts.
  10. 14. Cells that have specific structural adaptations to efficiently carry out a particular role in an organism.
  11. 16. A specialised cell that has long axons to carry electrical messages long distances.
  12. 18. Single celled organisms such as Salmonella.
