TAXONOMY
The branch of
Science that
formally names and
classifies organisms
by their structure,
function and
relationships.
DOMAINS
All forms of life are
classified into 3
Domains. This
based on their
characteristics. It’s
the BROADEST level
of organization.
They are….
Bacteria, Archaea
& Eukarya
KINGDOM
Biologist have
organized all living
things into 6 large
groups called
Kingdoms. They are
classified based on
their specific
characteristics.
6 Kingdoms: Archaea,
Bacteria, Plant,Animal
Fungi, and Protista
DOMAIN: ARCHAEA
KINGDOM: ARCHAEA BACTERIA
Domain Archaea only has ONE Kingdom…Archaea
bacteria. They come from EXTREME environments.
Most die in the presence of oxygen.
All organisms in the Archaea bacteria Kingdom must
be:
Unicellular
Prokaryotic
Autotrophic and Heterotrophic
Asexual and Sexual Reproduction
DOMAIN: BACTERIA
KINGDOM: EUBACTERIA
Domain Bacteria only has ONE Kingdom…Eubacteria.
They live in many different environments. Some need
oxygen, but others die in the presence of oxygen.
All organisms in the Eubacteria Kingdom must be:
Unicellular
Prokaryotic
Autotrophic and Heterotrophic
Asexual and Sexual Reproduction
DOMAIN: EUKARYA
KINGDOMS: ANIMAL,
PLANT, FUNGI,
PROTISTA
This Domain contains the most
Kingdoms…4 total. All of the
Kingdoms contain organisms
that are Eukaryotic. Hence the
name Eukarya Domain.
The 4 Kingdoms are:
Plant
Animal
Fungi
Protista
DOMAIN: EUKARYA
KINGDOM: PLANT
All cells have Nucleus and a Cell Wall.
Ex: mosses, ferns, flowering plants, trees,
bushes
They are:
Multicellular
Eukaryotic
Autotrophic
Asexual and Sexual Reproduction
DOMAIN: EUKARYA
KINGDOM: ANIMAL
This kingdom is the one that you
belong to. All organisms in this
kingdom can be divided into
vertebrates and invertebrates.
Ex: insects, fish, humans, worms,
starfish, dogs, cats, pig, dolphin
They are:
Multicellular
Eukaryotic
Heterotrophic
Asexual and Sexual
Reproduction
DOMAIN: EUKARYA
KINGDOM: FUNGI
Some may confuse Fungi with
Plants, but they are NOT plants.
Fungi are decomposers, but like
plants they do have a cell wall.
Ex: Yeast, mold, mushrooms
They are:
Unicellular and Multicellular
Eukaryotic
Heterotrophic
Asexual and Sexual
Reproduction
DOMAIN: EUKARYA
KINGDOM: PROTISTA
Protista can be complicated.
Some Protista in a dark
environment are heterotrophic,
but in light they are
autotrophic.
Ex: Amoeba, Euglena, Algae,
Diatom, and Paramecium
They are:
Unicellular and Multicellular
Eukaryotic
Autotrophic and Heterotrophic
Asexual and Sexual
Reproduction
