|
Definition
| Ways in which bacteria and archaea are similar |
|
|
Term
|
Definition
| main distinction between the bacteria and the archaea |
|
|
Term
|
Definition
| what the bacterial cell wall is composed of |
|
|
Term
|
Definition
| spherical shaped bacteria |
|
|
Term
|
Definition
|
|
Term
|
Definition
| helical or corkscrew shaped |
|
|
Term
|
Definition
| specific stain used on cell wall |
|
|
Term
|
Definition
| bacteria's cell wall is exposed to the environment |
|
|
Term
|
Definition
| surrounding the cell wall of bacteria, it's function is to attach the bacteria to a surface |
|
|
Term
|
Definition
| enables bacteria to movement by rotating this |
|
|
Term
|
Definition
| hair-like structures on the surface of certain bacteria that aid in attachment |
|
|
Term
|
Definition
| reproduction in prokaryotes is asexual in the form of this |
|
|
Term
|
Definition
| reproduction method in which the entire bacterial chromosome is replicated and passed on to each daughter cell |
|
|
Term
|
Definition
| the transfer of genetic information between two bacteria via a tube known as a sex pilus |
|
|
Term
|
Definition
| small, double-stranded ring of DNA that carries extrachromosomal genes in some bacteria; used in bacterial conjugation |
|
|
Term
|
Definition
| heat loving archaebacteria |
|
|
Term
|
Definition
| strict anaerobes that must live in environments without oxygen (archaebacteria) |
|
|
Term
|
Definition
| salt loving archaebacteria |
|
|
Term
|
Definition
| protective resting structures in which the bacterial chromosome is surrounded by a durable wall (in eubacteria; especially the bacilli) |
|
|
Term
|
Definition
| will persist on the eubacteria until conditions are favorable and then develop into a bacterium |
|
|
Term
|
Definition
| the two parts a virus must have |
|
|
Term
|
Definition
| the genetic information in a virus - can be either DNA or RNA |
|
|
Term
|
Definition
| a protein coat in viruses that surrounds and protects the genome |
|
|
Term
|
Definition
| optional part on viruses - a membrane that surrounds the capsid |
|
|
Term
| take control of a host cell to produce more virus particles |
|
Definition
| entire function of a virus |
|
|
Term
| No, because they require a host for their reproduction |
|
Definition
|
|
Term
|
Definition
| two possible reproductive pathways of viruses |
|
|
Term
|
Definition
1. virus attachment to cell surface
2. penetration of viral DNA into the cell
3. Replication and synthesis of viral components
4. new virus assembly
5. cell lysis and release of the virus |
|
|
Term
|
Definition
| allows reproduction of the virus without destruction of the host cell. The viral genome is incorporated into the bacterial host cell's genome |
|
|
Term
|
Definition
| the expression of the viral genes by a bacterial cell that changes the host's phenotype and usually results in the production of a toxin |
|
|
Term
|
Definition
| smaller than viruses, these are small fragments of ssRNA with no protein coat. Plant pathogens |
|
|
Term
|
Definition
| unusual infectious protein particles with no genetic material |
|
|
Term
|
Definition
| the widespread use and misuse of antibiotics has led to some pathogenic bacteria to develop this |
|
