Download Domains and kingdoms - Peoria Public Schools

The broadest
and most
general
category of
classification is
the DOMAIN
The three domains
are BACTERIA,
ARCHEA, and
EUKARYA
 Organisms
are
classified into
domains based on
their cell type and
structure
 Prokaryotes
with cell walls
containing peptidoglycan.
 Survive in many
environments
 Can be aerobic or anaerobic
 Can be autotrophs (make
their own food) or
heterotrophs
 More abundant than any
other organism
 Only kingdom is BACTERIA
 Thought
to be the oldest
organisms
 Diverse in shape and
nutrition requirements
 Some autotrophic, most
are heterotrophic
 They are extremophiles,
meaning that they live in
extreme environments
 Only kingdom is ARCHAEA
Organisms
with a
membranebound nucleus
Consist of the
kingdoms:
PROTISTA,
FUNGI, PLANTAE,
and ANIMALIA
 Eukaryotic
organisms
that can be unicellular,
colonial, or multicellular
 Classified into three
groups: Algae (plantlike), Protozoans (animallike) , and fungus-like
protozoans
 They can be autotrophic
or heterotrophic.
 Example: Paramecium
A
fungus can be
unicellular or
multicellular
 They absorb nutrients
from organic materials
in the environment
 Heterotrophs
 Lack motility (ability
to move)
 Have cell walls
 Example: Mushroom
Multicellular
Contain
cell walls
Contain chloroplasts
Mostly autotrophic with
a few heterotrophs
Possess cells organized
into tissue
Example: Moss
 Heterotrophic
 Multicellular
 No
eukaryotes
cell walls
 Cells are organized into tissues
 Mostly motile
 Example: Worm
Viruses are motile and contain
genetic material, but are not placed
in a classification category.
This is because viruses do not
contain cells, so they are not
considered living. They are made of
nucleic acid surrounded by protein.
