| Front | Draw out a typical prokaryotic cell with all its organelles. What defines prokaryotic cells and briefly describe the function of each organelle |
|---|---|
| Back | Prokaryotes are always single called organisms with no true nucleus and no membrane bound organelles Chromosomal DNA: supercoiled long chain of circular DNA plasmids: small circular loops of DNA Flagellum: hollow cylindrical thread like structures that rotate to move cells Pili: thin protein tubes allowing bacteria to adhere to surfaces Ribosomes: site of translation to produce proteins Capsule: slimy layer on surface for protection to prevent dehydration Cell wall: contains peptidoglycan (combination of polysaccaride and polypeptide) Cell surface plasma membrane: control movement in/out of cells mesosome: infolding of cell surface membrane site of respiration reactions for energy (Cyanobacteria photosynthesise so also have chloroplasts) |
