Virus and Bacteria Test Review • Eubacteria – Found everywhere, have peptidoglycan in • their cell walls. • Archaebacteria – Found in extreme environments such as • salty waters (Dead Sea), hot springs; do not have peptidoglycan • in their cell walls. • 2.
3. Gram positive – Have a thick peptidoglycan layer in the cell walls; turn purple with Gram stain. Gram negative – Have a thin peptidoglycan layer in the cell walls; turn pink with Gram stain. 4. Bacteriophage 5. Capsid 6. Streptococci/Streptococcus 7. Retrovirus 8. Binary fission 9. Bioremediation 10. Prokaryotic 11. Bacilli 12. Chemoautotrophs
Lytic Lysogenic 13. • Does not destroy • host cell • Destroys • host cell Replication cycles 2. Takes over host cells to make viral DNA and Proteins (‘High jack’) 2. Viral DNA replicates with the host cell’s DNA. 14. Used to make food such as yogurt and cheese Used to make antibiotics Help with clean up of pollutants such as oil (bioremediation)
15. See chalk board 16. Attach to host cell, make conjugation bridges 17. Movement 18. Protects cell against drying out and host’s white blood cells. 19. Gives shape, protection 20. Carries genetic material. 21.No, a virus is not living. You can only treat the symptoms of a viral infection or get vaccinated.
22. Bacteria • Living cells • Contain cytoplasm • Cell wall around cytoplasm and DNA • Reproduce through binary fission and conjugation • Viruses • Do not have cells • Do not have cytoplasm • Capsid around DNA/RNA • Can only replicate (make a copy of) inside a host cell. Contain DNA (genetic material) Have different shapes Can be pathogens (cause illness)
