Biology Classification Review

The science of naming and grouping organisms is called

• anatomy

• taxonomy

• botany

• paleontology

In Linneaus's system of classifying organisms, orders are grouped together into

• classes

• species

• families

• genera

The largest and most inclusive of the Linnaean taxonomic ranks is the

• kingdom

• order

• phylum

• domain

A specific trait that is used to construct a cladogram is called a

• taxon

• structural feature

• clade

• derived character

The three domains are

• Animalia, Plantae, and Archaebacteria.

• Plantae, Fungi, and Eubacteria.

• Bacteria, Archaea, and Eukarya.

• Protista, Bacteria, and Animalia.

Which of the following kingdoms includes only heterotrophs?

• Protista

• Fungi

• Plantae

• Eubacteria

What characteristics are used to place an organism in the domain Bacteria?

• It is a prokaryote.

• It has cell walls with peptidoglycan.

• It is unicellular.

• All of the above are correct.

In the six-kingdom system of classifying living things, which kingdoms contain unicellular organisms?

• Eubacteria, only

• Eubacteria and "Protista" only

• Archaebacteria only

• Eubacteria, Archaebacteria, Plantae, "Protista" and Fungi.

A multicellular eukaryote without cell walls would be in which kingdom?

• Animalia

• Plantae

• Eukarya

• Fungi

An organisms with cell walls lacking peptidoglycan that can survive only in the absence of oxygen would be in which kingdom?

• Eubacteria

• Bacteria

• Archaea

• Archaebacteria
