Five-Kingdom System
Animal Kingdom – eukaryotic, multicellular, heterotrophs, no cell walls, Ex. invertebrates (without
backbones) and vertebrates (with backbones).
Plant Kingdom – eukaryotic, multicellular, autotrophs, have cell walls, Ex. mosses, ferns,
flowering and seed plants.
Fungi Kingdom – eukaryotic, most multicellular and some unicellular, heterotrophs (break down
other organic materials to obtain food), cells with cell walls but not green, Ex. mushrooms, molds,
and yeasts.
Protist Kingdom – eukaryotic, many are single-celled and others are multicellular, some
heterotrophs and others autotrophs, Ex. come in a wide variety of forms: animal-like, such as
amoeba, some are plant-like such as algae, and others are fungi-like.
.
Eubacteria Kingdom – prokaryotic, unicellular, some autotrophs while others heterotrophs,
Ex. bacteria and blue-green algae.
Arcaeabacteria Kingdom -- prokaryotic, unicellular, some autotrophs while others heterotrophs,
live in extreme conditions, Ex. bacteria living near ocean thermal vents or in a cow’s stomach
Seven Layers in each Kingdom
The classification of humans – Homo sapiens
The two part naming system is called Binomial nomenclature (consists of genus and species.).
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Primata
Family: Hominadae
Genus: Homo
Species: sapiens (note: species is not capitalized.)
