Overview of
Domains and Kingdoms
The most widely used biological
classification system has six
kingdoms within three domains.
There are three Domains:
Bacteria
Archaea
Eukarya
Organisms are classified into
domains according to
cell type and structure.
What are the two basic cell types,
and how do they differ?
If the organisms have a cell wall, it
might be made of
peptidoglycan,
cellulose, or
chitin
Organisms may exist as either
Unicellular,
Colonial, or
Multicellular
To get much-needed nutrition,
organisms might be
Autotrophs, or
Heterotrophs
Within the Domain Bacteria,
there is one Kingdom:
Eubacteria
Characteristics of Kingdom
Eubacteria include…
What is the cell type?
Is a cell wall present?
If a cell wall is present, does it
have peptidoglycan, cellulose,
or chitin?
Are the organisms unicellular,
colonial, or multicellular?
Are they autotrophs or
heterotrophs?
Find some pictures of Eubacteria
and paste them here (e.g.
Pseudomonas, tuberculosis, and anabaena).
Within the Domain Archaea, there
is one Kingdom:
Archaebacteria
Characteristics of Kingdom
Archaebacteria include…
What is the cell type?
Is a cell wall present?
If a cell wall is present, does it
have peptidoglycan, cellulose,
or chitin?
Are the organisms unicellular,
colonial, or multicellular?
Are they autotrophs or
heterotrophs?
Find some pictures of
Archaebacteria and paste them
here (e.g. Staphylothermus and Methanopyrus)
Within the Domain Eukarya, there
are four Kingdoms:
Protista
Fungi
Plantae
Animalia
Characteristics of Kingdom Protista
include…
What is the cell type?
Is a cell wall present?
If a cell wall is present, does it
have peptidoglycan, cellulose,
or chitin?
Are the organisms unicellular,
colonial, or multicellular?
Are they autotrophs or
heterotrophs?
Find some pictures of Protists and
paste them here (e.g. algae like kelp,
protozoans like Amoeba, and other protists like mildew
and Euglena)
Characteristics of Kingdom Fungi
include…
What is the cell type?
Is a cell wall present?
If a cell wall is present, does it
have peptidoglycan, cellulose,
or chitin?
Are the organisms unicellular,
colonial, or multicellular?
Are they autotrophs or
heterotrophs?
Find some pictures of Fungi and
paste them here (e.g. mushrooms, yeast,
molds, and those that cause athletes foot and
ringworm)
Characteristics of Kingdom Plantae
include…
What is the cell type?
Is a cell wall present?
If a cell wall is present, does it
have peptidoglycan, cellulose,
or chitin?
Are the organisms unicellular,
colonial, or multicellular?
Are they autotrophs or
heterotrophs?
Find some pictures of plants and
paste them here (e.g. moss, fern, and types of
flowers, bushes, and trees)
Characteristics of Kingdom
Animalia include ….
What is the cell type?
Is a cell wall present?
If a cell wall is present, does it
have peptidoglycan, cellulose,
or chitin?
Are the organisms unicellular,
colonial, or multicellular?
Are they autotrophs or
heterotrophs?
Find some pictures of animals and
paste them here (e.g. worms, coral, fish,
insects, spiders, and various types of amphibians,
reptiles, birds, and mammals)
