classification

Eubacteria

A group of prokaryotic, unicellular organisms with a cell wall; ecologically diverse and can be autotrophs or heterotrophs. Examples include Streptococcus and E. coli.

Archaebacteria

A type of prokaryotic, unicellular organism with a cell wall that lacks peptidoglycan; autotrophic or heterotrophic and typically found in harsh environments. Examples include methanogens and halophiles.

Protista

A kingdom of eukaryotic, mostly unicellular organisms that can be autotrophs or heterotrophs; some have a cell wall made of cellulose and chloroplasts. Examples include amoeba and paramecium.

Fungi

Eukaryotic, multicellular organisms that are heterotrophic, have a cell wall made of chitin, reproduce by forming spores, and lack chlorophyll. Examples include mushrooms and yeast.

Plantae

Eukaryotic, multicellular organisms that are autotrophic, contain chloroplasts, and have a cell wall made of cellulose.

Animalia

Eukaryotic, multicellular organisms that are heterotrophic, lacking both a cell wall and chloroplasts.
