Cell Structure

4. The site of protein synthesis
6. Controls what enters and leaves the cell
8. Found in only plant and bacterial cells and provides strength to the cell
10. The only type of cell which does not contain mitochondria
11. The site of aerobic respiration that provides energy to the cell
13. The only type of cell to contain chloroplasts
14. A liquid substance in which chemical reactions occur
15. Cells which have a circular strand of DNA not contained in a nucleus
16. The structures that make up plant cell walls
17. Small rings of DNA that may be found in bacterial cells
19. The microscope with the lowest magnification and resolution (so is used to view larger objects)
21. The type of electron microscope that produces 3D images

1. Cells that have the ability to differentiate throughout their lives
2. The process in which cells become specialised for a particular function
3. DNA in a cell is stored in this structure
5. Contains cell sap to help keep the plant rigid
7. The type of microscope used to view smaller objects such as mitochondria, ribosomes, chloroplasts and plasmids
9. Cells which have a nucleus containing DNA
12. The site of photosynthesis
18. The process in which a cell divides to produce two identical daughter cells
20. The type of electron microscope that produces 2D images detailing organelles
