What is taxonomy?

• The study of living thing

• the branch of science concerned with the classification of living organisms

• the study of how living things interact with their environment

• the branch of science concerned with studying the animal kingdom

Which of the 3 domains has membrane-bound organelles?

• Archaea

• Eukarya

• Bacteria

• Katara

The MAIN reason scientists classify living things is to:

• Determine which organisms are most dangerous

• Create an organized way to study relationships between organisms

• Decide which organisms are most important

• Separate living things from non-living things

Which characteristic is shared by ALL organisms in the Eukarya domain?

• They are multicellular

• They have a nucleus

• They can photosynthesize

• They are heterotrophs

Why do scientists use a classification system?

• To make organisms easier to count

• To create a universal way to identify organisms

• To determine which organisms are more important

• To separate living from non-living things

A scientist discovers a new single-celled organism that can survive in boiling hot springs. Which domain most likely contains this organism?

• Bacteria

• Archaea

• Eukarya

• Protista

What are the 7 levels in order used to classify organisms?

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

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

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

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

Which sequence best represents increasing complexity in cell organization?

• Bacteria → Archaea → Protist → Plant

• Archaea → Bacteria → Animal → Fungi

• Protist → Plant → Animal → Bacteria

• Animal → Plant → Bacteria → Archaea
