Why do scientists classify living things?

• It helps scientists trap species to study
• It is easier to study organisms when grouped 
• It is a good way to keep organisms calm
• It is helpful when dissecting an organism

The science of grouping and naming organisms

• Phylogeny

• Dichotomy

• Taxonomy

• Genetics

The taxonomic level that would include the MOST number of species

• class

• kingdom

• phylum

• genus

What characteristics are used to divide organisms into kingdoms?

• number of cells, nucleus, obtaining energy

• number of legs, mammal, reptile

• obtaining energy, habitat, nucleus

• number of cells, eggs or live birth, aquatic or terrestial

Which 2 organisms would be able to reproduce and produce fertile offspring?

• 2 organisms in the same class

• 2 organisms in the same family

• 2 organisms in the same genus

• 2 organisms in the same species

Scientists around the world use a standardized taxonomic system. Why would scientists want to use a taxonomic system that is standardized?

• In order to avoid confusion with the identification of organisms

• Because Linnaeus established the system

• So that Latin names can be applied for a practical purpose

• In order to place organisms in different groups
