Microbio

bacteria

unicellular prokaryotes with a peptidoglycan cell wall, binary fission

archaea

nonpathogenic prokaryotes that live in extreme environments

archaea types

metanogens, halophiles, thermophiles

fungi

eukaryotes, chitin cell wall, absorbs organic material

protozoa

unicellular eukaryotes, can be parasitic, moves by pseudopods and flagella

algae

photosynthetic eukaryotes, cellulose wall, produce oxygen and carbohydrates

virus

acellular, DNA/RNA core, can only reproduce with host

helminths

multicellular animal parasite (like worms)

3 domains

bacteria, archaea, eukarya

Francesco Redi

disproved spontaneous generation with maggots and meat jars

Louis Pasteur

proved biogenesis with beef broth

fermentation

yeast convert sugars to alcohol in absence of air

souring

bacteria convert alcohol to vinegar
