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 The Hierarchical System
Kingdom Phylum Class Order Family Genus Species

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

6 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

7 Examples of Common Scientific Names
Canis familiaris - dog Felis domesticus - cat Canis lupus - wolf Vulpes vulpes - fox Populus deltoides - cottonwood

8 There are estimated to be 5-10 million species in this world.
We have scientifically identified 1.5 million of them.

9 THE FIVE KINGDOMS Monera Protista Fungi Plantae Animalia

10

11 Monera Prokaryotic Unicellular Bacteria

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

13 Fungi Eukaryotic Chitin in wall (soft cell wall) Heterotrophic
Reproduce by spores

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

15 Animalia Eukaryotic Multicellular Cells without walls Heterotrophic
