A | B |
Lactobacillus | bacteria used to make yogurt |
virus | small particle that infects living things |
capsid | protein coat surrounding a virus |
structure of virus | DNA or RNA surrounded by protein coat |
lytic cycle | viral DNA causes host cell to make more virus |
lysogenic cycle | viral DNA incorporates into host DNA |
Archaebacteria | 1-celled prokaryotes that lack peptidoglycan/live in harsh environments |
Eubacteria | one-celled prokaryotes with peptidoglycan in cell walls/familiar |
E.coli | eubacteria that inhabit large intestine |
streptococcus | eubacteria that causes strep throat |
streptomyces | eubacteria that produces antibiotic |
structure of bacteria | cell wall, cell membrane, DNA, ribosomes |
peptidoglycan | found in cell walls of Eubacteria |
coccus | round or oval-shaped bacteria |
bacillus | rod-shaped bacteria |
spirillum | spiral-shaped bacteria |
antibiotics | substances that prevent bacteria from reproducing/growing |
saprobes | heterotrophic bacteria that live on dead organisms |
parasites | heterotrophic bacteria that live on or in living organisms |
binary fission | bacteria reproduces by replicating DNA and dividing into 2 equal-sized cells |
conjugation | 2 bacteria form bridge of cytoplasm, exchange DNA, divide by binary fission |
endospores | protective coating formed by some bacteria when conditions are hostile |
reproduction | only life process carried out by virus |
herpes simplex virus | causes cold sores (lysogenic) |
rhinovirus | causes common cold (lytic) |
shingles | occurs when chicken pox virus switches back to lytic cycle |
obligate aerobes | bacteria that require oxygen |
obligate anaerobes | bacteria that cannot live in the presence of oxygen |
facultative aerobes | bacteria that can use aerobic or anaerobic respiration |
bacteriophage | virus that infects bacterial cells |
