Prokaryote and Passive Transport Review Answers 1. False: animal cells don’t have cell walls and bacteria do! 2. True 3. Eubacteria and Archaebacteria 4. Archaebacteria 5. Nucleus (pro = no!) 6. Bacilli = rod-like shape, cocci = shere-like shape, spirilla = spiral-like shape 7. Diplo= pairs, Strepto= chain, staphylo= clumps 13. Photoautotrophs use light from the sun to make their own food. 16. Using energy from chemicals to make sugars(food) 17. Mutualisim = BOTH benefit 18. Homeostasis = a steady-state, equilibrium 19. Cell membrane = a semi-permeable, lipid bi-layer 22. Diffusion= movement of molecules from a high concentration to a low concentration 23. Osmosis = the diffusion of water 24. Hypertonic = there is more salt/sugar in the solution than in the cell so water will move OUT of the cell = cell shrivels. Hypotonic = there is less salt/sugar in the solution than in the cell so water will INTO the cell = cell bursts. Isotonic = equal amounts of salt/sugar so water moves in and out of cell equally = cell stays the same 25. 2 molecules of water need to move to side A there would be an equal amount of 9 water molecules on both sides. 2 sugar molecules would move to side B so there would be an equal amount of 6 sugar molecules on both sides. 26. Bacteria need food, moisture, and warmth to grow. 27. True 28.
