1.2 Ultrastructures

2. the size of eukaryotic ribosomes.
5. a region of the prokaryotic cell where DNA is located.
8. Contain stroma, thylakoids and a double membrane and the site of photosynthesis reactions.
12. endoplasmic reticulum 3 words. The site of synthesis of proteins destined for export or for secretion.
13. fission method of prokaryotic cell division.
15. 2 words. photosynthetic tissue below the epidermis in a leaf.
17. 2 words. Often made of cellulose or peptidoglycan. A non-living carbohydrate-based extracellular material.
18. DNA not associated with histones or histone-like proteins.
19. endoplasmic reticulum with ribosomes attached.
20. organisms with membrane-bound organelles including nuclei.
23. endoplasmic reticulum that synthesizes lipids, including new membrane and does not have ribosomes attached.
24. category of a cell without a membrane-bound nucleus: archaea and bacteria.
25. Bud off the rER and golgi on their way to take materials to the cell membrane for secretion. Also used to transport materials inside the cell.

1. extra-chromosomal DNA in a prokaryote.
3. a (relatively) long extension of the cell used in locomotion.
4. seen in eukaryotes; consequence of organelles being membrane-bound.
6. 2 words. a eukaryotic organelle that modifies and sorts proteins. It is like the post office of the cell.
7. the size of prokaryotic ribosomes.
9. Glands that secrete their products into ducts.
10. a sub-cellular structure or membrane-bound compartment with a distinct structure and function.
11. Contain matrix, cristae and produce ATP in respiration as the energy currency of the cell.
14. the detailed structure of a biological entity.
15. extensions of the prokaryotic cell surface membrane used for reproduction.
16. membrane-bound organelle found in eukaryotes that contains DNA; it is the site of replication and transcription.
21. Contain digestive enzymes for breaking down materials in the cell.
22. Sythesises proteins using amino acids.
