 Which of the observations below comes clsest to explaining the basis for placing these organisms in different taxa | Their cell walls are constructed from very different biochemicals |
| Which of the following is the most common compound in the cell walls of gram positive bacteria | Peptidoglycan |
| Plant like photosynthesis that releases 02 occurs in | Cyanobacteria |
| Which of the following is the correct order, from most external to most internal? | Capsule, Cell Wall, Plasma membrane |
| This is because bacteri that encounter such an environment | Undergo death by plasmolysis |
| Which two structures play direct roles in permitting bacteria to adhere to each other, or to other surfaces? | Capsules and Fimbriae |
| Prokaryotes have ribosomes different from those of eukaryotes. Because of this which of the following is true? | Some selective antibiotics can block protein synthesis of bacteria without harming the eukaryotic host |
| What was the basis for diving prokaryotes into two domains | Molecular characteristics such as ribosomal RNA sequences |
| Which of the following traits do archae and bacteria share | Presence of plasma membrane and lack of a nuclear envolope |
| If penicillin is an antibiotic that inhibits enzymes from catalyzing the synthesis of peptidoglycan, then which prokaryotes should be most vulnerable to inhibition by penicillin? | Gram positive bacteria |
| In which of the following ways can prokaryotes be considered to be more successful on Earth than humans? | Prokaryotes are much more numerous and have more biomass and Prokaryotes occupy more diverse habitats. |
| If all the bacteria on Earth suddenly disappeared which of the following would be the most likely and most direct result? | The recycling of nutrients would be greatly reduced at least initially |
| The prokaryotic cells that built stromatolites are classified as | Cyanobacteria |
| An example of bioremediation is | The use of prokaryotes to treat sewage or clean up oil spills |
| Composed almost entirely of peptidoglycan | Endospore |
| Requires ATP to function, and permits some species to respond to taxes | Flagellum |
| Not present in all bacteria , this slimy material enables cells that possess it to resist the defenses of host organisms | Capsule |
| Not present in all bacteria, this structure enables those that possess it to resist the defenses of host organisms | Endospore |
| Responsible for high levels of O2 in Earths Atmosphere | Photoautotrophs |
