Identify the correct level of classification from MOST specific to LEAST specific.

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

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

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

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

All organisms that have cells with a nucleus are classified in the ____________ Domain.

• Archaea

• Eukaryota

• Bacteria

• Protista

The method used to classify living organisms into groups is called:

• taxonomy

• binomial nomenclature

• evolution

• Darwinism

The separation of the Archaea into a separate domain indicates that

• organisms should never be classified according to how they appear.

• microscopes have greatly improved so that we can better view them.

• early biologists rushed to classify them without closely examining them.

• these organisms are very different from bacteria and from eukaryotes.

What do all of the organisms classified into the two Domains, Bacteria and Archaea, have in common?

• They are all multi-celled organisms.

• They are all organisms within the same kingdom.

• They are all made up of multi-celled organisms with membrane bound organelles.

• They are all made up of only single-celled organisms that lack membrane bound organelles.

The five-kingdom system of classification reflects the idea that all organisms can be separated into two main groups: prokaryotes and eukaryotes. The new six-kingdom system recognizes three broader groups called domains, that include six kingdoms.  How does the domain Eukarya differ from the other two domains?

• All organisms in the domain have eukaryotic cells.

• All organisms in the domain are heterotrophic.

• All organisms in the domain are multicellular.

• All organisms in the domain have prokaryotic cells.

Some species of present day protists contain living organisms within their cytoplasm. Paramecium bursaria are hosts for zoochlorellae, photosynthetic protists, that live within the cytoplasm of the paramecium. The relationship appears to be symbiotic; the zoochlorellae gain protection and possibly some essential nutrients from the host cytoplasm and the paramecium host has an available food source when its usual food source is depleted.  This symbiotic relationship provides support for the theory of endosymbiosis, which states that:

• mitochondria and chloroplasts evolved from small prokaryotes living within larger cells.

• animal-like cells evolved from ancestors that were photosynthetic.

• photosynthetic organisms, like today's land plants, evolved from photosynthetic bacteria.

• heterotrophic organisms could not have evolved before the evolution of photosynthetic organisms.

A cladogram is diagram that shows the relationship among organisms according to a common ancestor and specific characteristics. The farther away an organism is from the point of origin, the less closely related to that common ancestor it is.

Study the cladogram. Which statement is true regarding the organisms on the cladogram?

• The salmon is more closely related to the hamster than the lizard.

• These organisms do not have a common ancestor.

• The salamander has lungs, but not claws or nails.

• The chimpanzee is more closely related to the salamander than the lizard.

A phylogeny of some land plants is shown. Which statement correlates accurately with the tree shown?

• Clubmosses are the common ancestor to all other land plants.

• Spikemosses and quillworths have nearly identical DNA sequences.

• Flowering plants and ferns have a more recent common ancestor than either has with spikemosses.

• Ferns and flowering plants both produce seeds.
