Year 12 Cells Revision

3. The site of photosynthesis.
11. Helps prokaryotes cling to each other and to various surfaces in their environment.
13. Involved in the production, processing and storage of lipids, carbohydrates and steroids.
14. Is an irregularly shaped region within the prokaryotic cell that contains all or most of the genetic material.

1. Sac in plant cells surrounded by the tonoplast, selectively permeable membrane.
2. Modifies proteins and lipids before packaging them into Golgi vesicles.
4. Controls the exchange of materials between the internal cell environment and the external environment.
5. Processes proteins made by the ribosomes.
6. Site of translation (protein synthesis).
7. Formed outside of the cell membrane and offer structural support to cell.
8. Small rings of double-stranded extra-chromosomal ("outside the chromosome") DNA.
9. Contains chromatin (a complex of DNA and histone proteins) which is the genetic material of the cell.
10. The site of aerobic respiration within eukaryotic cells.
12. The site of ribosome production.
