Archaea (bacteria that lives in very hot, very acidic conditions, etc) was added to the original two domains of Bacteria and Eukarya

What is correct about the hierarchy of the taxonomic system currently used to classify organisms?

• Many different orders of organisms make up the same species.

• Many different families of organisms make up the same order.

• Many different classes of organisms make up the same genus.

• Many different kingdoms of organisms make up the same phylum.

Why has the classification method of taxonomists changed over time?

• There's No guidelines as to how organisms may be classified.

• Some populations of organisms have unique biochemistry.

• Technology advances increase the amount of information known about different species

• New species are always being added to the bottom levels of classification systems.

Characteristics of the plant kingdom=

• eukaryotic cells, autotrophic, no cell wall

• prokaryotic cells, autotrophic, no cell wall

• eukaryotic cells, autotrophic, cell wall present

• prokaryotic cells, autotrophic, cell wall present

Earlier in the year we observed a sample of water. Some of us saw a single-celled organism digesting/eating/absorbing another cell. We saw the organism contained a nucleus and other organelles. What kingdom would this organism most likely be classified as?

• plantae

• protista

• animalia

• fungi

Earlier in the year we observed a sample of water. One student saw a green, one-celled organism that has a flagella. What was a safe inference the student made?

• it was able to move since it has a flagella.

•  it must be photosynthetic since it is green.

• has to be a decomposer since it is single-celled

• belongs to the animal kingdom since it has a flagella

Why do we now have 8 Taxonomic levels instead of 5, and 6 Kingdoms instead of 2 as in Carl Linnaeus' day? (1700's)

• Scientists didn't used to be able to make accurate observations.
• Plants and Animals have changed in 200 years.
• Scientists have better, more accurate tools to observe things.
• We don't need classification systems any more.
