Content: Archaebacteria, Schizophyta, Cyanophyta, Prochlorophyta
what phylum of bacteria is adapted to live in harsh environments? Archaebacteria
What are 3 kinds of Archaebacteria
methanogens, extreme halophiles, thermoacidophiles
what is the larges Moneran phylum
Schizophyta
What are the 4 classes of the phylum Schizophyta
Eubacteria, Actinomycota, Rickettsiae, Spirochaeta
Means without oxygen
anaerobic
Means with oxygen
aerobic
Means methane forming
methanogen
Archaebacterian that lives in the Great Salt Lake & Dead Sea
extreme halophile
what does halophile mean
salt loving
Archaebacteria that lives in the digestive tracts of sheep &cattle or on bottoms of bogs, lakes or sewage ponds
methanogen
Archaebacterian that lives in hot springs or in smoldering coal
thermoacidophile
What class is the most familiar bacteria in? Schizophyta
3 characteristics of gram negative bacteria
has outer covering, stains pink, difficult to treat with antibiotics
3 characteristics of gram positive bacteria
lacks outer covering, stains purple, can be treated with antibiotics
What are the smallest bacteria? mycoplasmas
What class are the mycoplasma bacteria in? Eubacteria
What phylum are the mycoplasma bacteria in? Schizophyta
A gram + bacteria that causes diphtheria & TB
Actinomycota
Class of bacteria that decompose dead plants & animals
Actinomycota
What class of bacteria is a source for some antibiotics? Actinomycota
What class of bacteria is classified by their reaction to a gram stain test? Eubacteria
A test that uses a dye to stain the bacterial walls
gram stain test
parasitic gram - bacteria
Rickettsiae
Spiral shaped bacteria that use flagella to move
Spirochaeta
Class of bacteria that is carried by insects and transmitted to mammals
Rickettsiae
Class of bacteria that cause diseases like syphilis & Lyme disease
Spirochaeta
Phylum of blue green bacteria
Cyanophyta
Phylum of bacteria with traits similar to plants
Cyanophyta
Specialized cells that convert nitrogen from the air to a usable form
heterocysts
A population explosion of bacteria that will discolor lakes, rivers & parts of oceans
bloom
A photosynthetic bacteria that live symbiotically with marine organisms
Prochlorophyta
Small circular strands of DNA capable of replicating independently
plasmids
Protective layers around the walls of bacteria
capsules
A net of polysaccharides that help them stick to rocks, & host cells
glycocalyx
Protein strands used to attach themselves to things & may be used in reproduction
pili
A tough covering around the DNA that protects it when conditions are bad
endospore
Term referring to an organism that feeds on dead or decaying organic matter
saprophyte
Term for organisms that use sunlight to make their own food
photoautotroph
Term for organisms that use the energy of chemical reactions instead of sunlight to make own food
chemoautotroph
Cannot survive in the presence of oxygen
obligate anaerobe
Cannot survive without oxygen
obligate aerobe
Can live with or without oxygen
facultative anaerobe
List 4 things that can inhibit the reproduction of bacteria
heat, cold, predation, lack of food
2 methods of reproduction
binary fission, conjugation
An asexual form of reproduction in which the cell splits
binary fission
Occurs when the genetic information of 2 monerans of the same species is combined
conjugation
any organism that causes a disease
pathogen
a poisonous substance that disrupts the metabolism of an infected organism
toxin
What are 2 main kind of bacterial toxins
endotoxin & exotoxin
Toxin found in gram - bacteria that cause fever, weakness & circulatory damage
endotoxin
toxin produced by bacteria metabolism of bacteria & secreted around it
exotoxin
what kind of toxin are some of the most potent poisons known
exotoxin
chemicals that can inhibit the growth of some bacteria
antibiotic
