Overview of Domains and Kingdoms

The most widely used biological classification system has six

kingdoms within three domains.

There are three Domains:BacteriaArchaeaEukarya

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 eitherUnicellular,Colonial, or

Multicellular

To get much-needed nutrition, organisms might be

Autotrophs, orHeterotrophs

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:

ProtistaFungi

PlantaeAnimalia

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)
