CLASSIFICATION SYSTEMS

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

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

Begins very broad, ends specific

The Hierarchical System Kingdom Phylum Class Order Family Genus Species

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

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

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

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!

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

Monera Prokaryotic Auto- Hetero- and Chemo- Unicellular Bacteria

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

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

Plantae Eukaryotic Multicellular Cells with cellulose in cell wall Autotrophic Photosynthetic

Animalia Eukaryotic Multicellular Cells without walls Heterotrophic
