Cells

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.
18. Type of cell that contains chloroplasts and a cell wall made of cellulose.
19. In plants this organelle is very large and used to store water, sap and waste products.

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.
