Domain 3 – Classification: 15-Question Assessment

Scientists classify organisms because:

• it helps organize and understand the diversity of life

• it makes organisms look more interesting

• it increases the number of species

• it is required by law

The classification levels from most broad to most specific are:

• Kingdom, Phylum, Class, Order, Family, Genus, Species

• Species, Genus, Family, Order, Class, Phylum, Kingdom

• Order, Class, Phylum, Kingdom, Family, Genus, Species

• Genus, Species, Family, Order, Class, Phylum, Kingdom

The correct way to write a scientific name is:

• Italicized with the genus capitalized and species lowercase (eg. Homo sapiens)

• All uppercase letters

  (eg. HOMO SAPIENS)

• All lowercase letters without italics (eg. homo sapiens)

• Genus and species both capitalized (Homo Sapiens)

The domain that contains organisms with membrane-bound organelles is:

• Bacteria

• Eukarya

• Archaea

• Monera

The kingdom that includes organisms that are multicellular, photosynthetic, and have cell walls made of cellulose is:

• Fungi

• Plantae

• Animalia

• Protista

The characteristic that best distinguishes Archaea from Bacteria is:

• Differences in cell wall composition

• Presence of a nucleus

• Ability to photosynthesize

• Multicellularity

Scientists classify organisms by comparing their characteristics. The MOST reliable type of characteristic for determining evolutionary relationships is:

• Physical appearance

• Habitat preference

• Genetic information

• Dietary habits

Two organisms look very similar but have very different DNA sequences. This suggests that:

• they are not closely related despite their appearance.

• they are the same species.

• they have identical evolutionary histories.

• they must have similar DNA.

Viruses are not considered living organisms because:

• they cannot carry out metabolic processes on their own.

• they have a cellular structure.

• they can reproduce independently.

• they are made up of multiple cells.
