2.  Genus  2 nd smallest grouping of classification  Genus name first letter is capitalized & genus is written in italics  Species  Smallest grouping of classification  Species name is written in italics

3.  Latin  Dead language  No longer spoken in everyday conversations, so it is not changing  Language of educated people of the time

4.  Animals  Plants  Eubacteria  Protists  Fungi  Archaebacteria

5.  Small, single-celled prokaryotic organisms  Usually has a cell wall & reproduce by cellular fission  Each bacteria has a cell wall, plasma membrane, cytoplasm with organelles, & at least one circular chromosome  No membrane-bound DNA so no “true” nucleus  Most bacteria are very small (about 2 μm)

6.  Prokaryotes  Autotrophs  Make their own food  Exist in harsh environments

7.  Eukaryotes that are not plants, animals, or fungi  Unicellular

8.  Eukaryotes  Heterotrophs (don’t produce their own food)  Unicellular or multicellular

9.  Eukaryotes  Multicellular  Autotrophs

10.  Eukaryotes  Multicellular  Heterotrophs  Symmetrical body organization  Sexual Reproduction  Movement

12.  Biochemistry-DNA & protein similarities  Fossil Record  Breeding behaviors  Geographic distribution  Embryonic development  Structural similarities

13.  The evolutionary history of a species or a taxon  Modern taxonomists are often involved in the analysis of the evolutionary or ancestral relationships among taxa  Biologist use fossils as important clues for finding out when evolutionary changes & divergence occurred  Compare homologous features between organisms, particularly organisms that share common ancestry

14.  Homologous features  Features that are similar because of shared or common ancestry  Analogous Features  Features that are similar because of similar function rather than common ancestry

15.  System of phylogenetic analysis that used shared & derived characters as the only criteria for grouping taxa  Shared Character  Feature that all members of a group have in common (feathers in birds)  Derived Character  A feature that evolved only within the group under consideration (find only feathers in birds throughout fossil record)

17.  Body arrangement in which parts that lie on opposite sides of an axis are identical  Radial symmetry  Body plan in which the parts are organized in a circle around an axis  Bilateral symmetry  Right & left symmetry  Asymmetrical  No symmetry

19.  Heterotrophs  Organisms that get their energy from other organisms  Autotrophs  Organisms that make their own energy
