| Term | Definition |
|---|
| Virus | name means poison, first studied on tobacco plants, much smaller than bacteria, can hide for a period of time to wait for conditions to become right again and then reoccur, host specific making it hard to treat, mutates quickly, cannot reproduce on own b/c it only has DNA or RNA, needs another cell to reproduce itself |
| Anatomy of a Virus | Segment of nucleic acid with a protein coat |
| Capsid | VIRUS protein coat containing DNA or RNA |
| Envelope | VIRUS covering on the outside of the capsid that helps enter the cell |
| Shape of viruses | geometric |
| Helical | VIRUS spiral |
| Polyhedral | many sided- virus for common cold is this |
| Pathogenic | causes disease in organisms |
| Lytic infections | fast infection |
| Lysogenic infection | slow infection |
| Archaebacteria | A kingdom of bacteria, live in hot places |
| Eubacteria | true bacteria, a kingdom of bacteria |
| bacteria | prokaryotes, 1 micron in size, single cell, have plasmid, reproduce by binary fission or conjugation |
| Life style | the more dangerous life style an organism has, the more ways it can reproduce |
| Binary fission | BACTERIA asexual, replication, cell divides in 2 daughter cells (you survive offspring does too) |
| Conjugation | BACTERIA sexual, + and - mating types join and exchange DNA (new traits, might adapt and survive) |
| anaerobic bacteria | does not require oxygen, causes food poisoning and tetanus |
| aerobic bacteria | require oxygen ex: B.subtilis, etal |
| Number of bacteria structures | 3 |
| Basic bacteria shapes | BACTERIA coccus, bacillus, spirillum |
| Arrangement of Bacteria | BACTERIA diplo, staphylo, strepto |
| coccus | BACTERIA round shape |
| bacillus | BACTERIA rod shape |
| spirillum | spiral shape of bacteria |
| diplo | 2 bacteria |
| staphylo | group of bacteria |
| strepto | chain of bacteria |
| Structures of bacteria | cellwall, capsules, endospores, pili |
| Capsules | structure outside cell wall of a bacteria |
| endospore | BACTERIA (structure for harsh conditions) forms around DNA |
| Pili | BACTERIA points adhere to surfaces |
| Gram stain | Use to indentify bacteria, doctors use to tell which antibiotics to give patients |
| Positive gram stain | purple |
| Negative gram stain | pink |
| Illness | Caused by toxins (chemicals) released by bacteria |
| antibiotics | medicines to treat bacteria |
| non pathogenic | not disease causing |
| plasmid | circular DNA |
