-organized according to type of cells, ability to
make food, number of cells in body
Archaebacteria
Eubacteria
Protista
Fungi
Plants
Animals
Terminology
Mode of nutrition (Getting food)
autotrophs – make own food
hetertrophs – get food from other sources
Cell type
prokaryotic – no nucleus
eukaryotic – with a nucleus
Terminology continued
Number of cells
unicellular – made of only one cell
multicellular – made of more than one
cell;
-have cells with special functions
Archaebacteria
-”ancient bacteria”
-existed before dinosaurs
-live in extreme environments
-hot springs
-acidic environment
-methane
-unicellular prokaryotes
-some autotrophs, some heterotrophs
-cell walls without peptidoglycan
Eubacteria
Chemical makeup is different from that of
archaebacteria.
-unicellular prokaryote
-some autotrophs, some heterotrophs
-cell walls with peptidoglycan
Protists
-“odds and ends” kingdom because its
organisms are pretty different from one
another
-most unicellular, some multicellular
-eukaryotes
-some autotrophs, some heterotrophs
-cell walls of cellulose in some
Fungi
-mushrooms, mold, and mildew
-most are multicellular, some (like yeast) are
unicellular
-eukaryotes
-all are heterotrophs
-eat dead or decaying organisms
-cell walls of chitin
Plants
-all plants are
multicellular
-all are eukaryotes
-plants are autotrophs
-cell walls of cellulose
Animals
-all are multicellular
-all are eukaryotes
-all are heterotrophs
-no cell walls
Domains
Bacteria: unicellular and prokaryotic, cell
walls contain peptidoglycan
 Archaea: unicellular and prokaryotic, no
peptidoglycan in cell walls
 Eukarya: have a nucleus

