6 kingdoms : animalia, bacteria, fungi, protista, archaea, plantae

three domains : bacteria, archaea, eukarya

eukarya contains plantae, animalia, fungi & protista, all kingdoms are eukaryotic

bacteria / archaea are both prokaryotic

plants v. animals : plants photosynthesize therefore making them different kingdoms

classifying kingdoms : number of cells, cell wall material, nutrition (autotroph/heterotroph) and reproduction.

autotroph : captures energy from sunlight/abiotic substances (plants & sunlight)

heterotroph : obtains energy by consuming other organisms (humans & meat)

autotrophic ≠ photosynthetic

Bacteria : single celled prokaryotes, some are photosynthetic, live in a moist environment, peptidoglycan is found inside them (e. coli, streph throat)

Archaea : single celled prokaryotes, lives in harsh environments (extremophile), first organism to evolve on earth (halophiles)

protists : unicellular colonies of cells, most diverse kingdom, heterotroph and autotroph (amoeba, algae)

fungi : always heterotrophic most are multicellular, no chloroplats, cell wall made of chitin (ky-tin), (mushrooms, yeast)

plants : multicellular, eukaryotic, terrestrial, cell wall made of cellulose (rose, tree)

animals : multicellular, eukaryotic, no cell wall (sponge, whale)
