1 CLASSIFICATION SYSTEMS

2 TAXONOMY aka “systematics” the study of the classification of all living things

3 WHY CLASSIFY? Sets up an organized system so scientists can communicate. Shows evolutionary linkages between organisms.

4 Begins very broad, ends specific

5 The Hierarchical System
Kingdom Phylum Class Order Family Genus Species

6 BINOMIAL NOMENCLATURE the system used to identify all organisms using a two part Latin name

7 Keys to Binomial Nomenclature
Felis domesticus Must be in Latin Must be in italics or underlined Genus (1st word) must be capitalized Species must be lowercase

8 Examples of Common Scientific Names
Canis familiaris - dog Spinus tristis- gold finch Canis lupus - wolf Vulpes vulpes - fox Populus trichocarpa- cottonwood

9 Estimated 80% have not been discovered yet!
There are estimated to be 10 million species in this world (2017EarthSky). Estimated 80% have not been discovered yet!

10 Protista (cells w/ nucleus)
THE FIVE KINGDOMS Monera (bacteria) Protista (cells w/ nucleus) Fungi Plantae Animalia

12

13 Monera Prokaryotic Auto- Hetero- and Chemo- Unicellular Bacteria

14 Protista Eukaryotic Single celled / simple multicellular
Heterotrophs and Autotrophs Includes organisms that “don’t fit”

15 Fungi Eukaryotic Heterotrophic Reproduce by spores
Largest organism on Earth (2.4 miles)

16 Plantae Eukaryotic Multicellular Cells with cellulose in cell wall
Autotrophic Photosynthetic

17 Animalia Eukaryotic Multicellular Cells without walls Heterotrophic
