Taxonomy
The scientific study on how living things are classified
Founders of classification
Aristotle, carlous linneous, Geourge E fox
8 levels of classification
Domain kingdom phylm Class order family genus speicies
Domain
The highest rank o organisms in a biological taxonomy domains divide all cellur life forms into three groups Archea bacteria eukaryote
Domain archea
unicellular organisms prokaryotes no nuclear membrane found in extreme envirements salty water volcanic hot springs archea bacteria
Domain bacteria
found everywere prokaryotes no nuclear membrane eubacteria
domain eukarya
found everywhere most of the world’s living tings eukaryotes cell has a nucleas prosista fungi animilea plantae
kingdom eubacteria
true bacteria prokarotic uniclellular autoatrophs and heterotrophs rod shaped found in soil roks ocean snow and living organisms
kingdom archea bacteria
differs from other bacteria prokaryotic unicellular autroph and heterotoph diffrent archea bacteria are found in these extreme envierments
kingdom protists
cannot be classified as animals plants or fungus eukaryotes most are unicellulare and h slime mold
kingdom fungi
multicellular eukaryotes H consumers yeast mushrooms
kingdom plantae
multicelular most live on land A producers provides for H
Kingdom animilea
Muticellular eukaryotes lives everywhere H consumers
