Taxonomy & Classification Test Review

Which levels of the standardized taxonomic system are used assign one name to a species?

• Domain

• Kingdom

• Genus

• Species

Answer explanation

Genus and Species groups are used to assign a scientific name.

A scientific name will avoid the confusion that common names create.

What do scientist do to avoid confusion when discussing an organism?

• Avoid using common names

• Discuss the common ancestors

• Assign a scientific name

• Discuss which Kingdom the organisms is in

Answer explanation

Which characteristic will distinguish a bacteria cell from an protist cell

• single-celled

• nucleus

• no nucleus

• cell wall

Answer explanation

Both Protist and Bacteria can be single celled and they both can have a cell wall.

However, Protist have a nucleus (Eukaryotic) and Bacteria lack a nucleus (Prokaryotic).

True or False: More than one organism can share a genus group, but only one can belong in a species group.

• True

• False

Organisms that can have a flagella are: Bacteria, Protists, and one Animal cell type (sperm)

What is the chemical composition of a Plant cell wall?

• Cellulose

• Chitin

• Peptidoglycan

• Starch

Answer explanation

Plant cell walls have cellulose.

Fungi cell walls have chitin

Eubacteria cell walls have peptidoglycan.
