taxonomy Flashcards
domain bacteria - kingdom eubacteria
prokaryotes, unicellular, auto, or heterotroph
domain archaea - kingdom archaebacteria
prokaryote, unicellular, auto, or heterotroph, lives in extreme areas
domain eukarya - kingdom Protista
eukaryote, some’ve cell walls, most uni- some multi-, auto, or heterotroph, ex: amoeba, giant kelp
domain eukarya - kingdom fungi
eukaryote, cell walls of chitin, most multi- some uni-, heterotroph, ex: mushrooms, yeasts
domain eukarya - kingdom Plantae
eukaryote, cell walls of chloroplast, multicellular, autotroph, ex: mosses, flowering plants
domain eukarya - kingdom Animalia
eukaryote, no cell walls, multicellular, heterotroph, ex: worms, mammals, fishes
viruses
non-living organisms that invade living organisms & can only reproduce within host cell
can viruses be cured
no & are not affected by antibiotics
virus reproductive cycles
lytic & lysogenic
what is the lytic cycle
Attacks your cell right away and makes you sick immediately; you only get better when your immune system finishes fighting off the virus. (ex: common cold, flu)
what is the lysogenic cycle
The virus injects its DNA into the host cell and then lies dormant (asleep) for a period of time. Every
time the host cell divides (mitosis), it will divide with the viral DNA. When it “wakes up,” the virus enters
the lytic cycle and attacks other living cells. (Ex: HIV -> AIDS, herpes)
what is the outermost layer of a virus
capsid
are viruses highly specific to the cells they infect?
yes
lytic cycle process
attachment > entry > replication > assembly > lysis
genus + species
scientific name
