Biology 17.3: Domains and Kingdoms

Domain that is thought to be more ancient than bacteria and yet more closely related to eukaryote ancestors.

• Archaea

• Eukarya

• Protista

• Fungi

True or False: Archaea are called extremophiles because they can live in extreme environments.

• True

• False

Mark the Kingdom that does NOT belong in Eukarya:

• Protista

• Bacteria

• Fungi

• Plantae

• Animalia

Mark the three domains used by biologists in the classification system:

• Fungi

• Bacteria

• Virus

• Archaea

• Eukarya

True or False: Bacteria are prokaryotes whose cell walls contain peptidoglycan, a polymer that contains two kinds of sugars that alternate in the chain.

• True

• False

These are eukaryotic organisms that can be unicellular, colonial, or multicellular:

• Fungi

• Animalia

• Protista

• Plantae

Mark the three groups of Protists:

• Algae

• Viruses

• Protozoans

• Euglenoids

• Extremophiles

This kingdom is made up of unicellular or multicellular eukaryotes that absorb nutrients from organic materials in their environment:

• Protists

• Fungus

• Plantae

• Animalia

Mark the characteristics of the members of the Fungi Kingdom:

• Autotrophic

• Heterotrophic

• Lack motility (ability to move)

• Have cell walls

• Extremophiles

Mark the characteristics of the Plantae Kingdom:

• Cell walls with cellulose

• Unicellular

• Multicellular

• Heterotroph

• Autotroph
