1 Classifying Organisms
Easier to Study! Classification The process of grouping thing based on similarities. Taxonomy The scientific study of how living things are classified

2 Naming Systems Aristotle Carolus Linnaeus 1707-1778
Carolus Linnaeus (Carl von Linné)                                    Naming Systems Carolus Linnaeus “Father of Taxonomy” Gave us system we use now Binomial Nomenclature two names Aristotle 5AD---1st to Classify Plants VS Animals herbs-shrubs-trees land-air-sea

3 Binomial Nomenclature
2 Names Genus and Species Scientific Name Written in italics. First word is capitalized and the second is not. Homo sapiens If handwriting the scientific name: Underline to show italics.

4 Genus Species Classification grouping that contains similar,
closely related organisms Species Group of similar organisms that can mate with each other and produce offspring that can also mate and Reproduce.

5 Most biologists classify organisms into 8 levels. Broad to Specific
More levels share more have in common

6 8 Classification Levels
Domain Broad to Specific Kingdoms Plyla Classes Order Families Genus Species Daily King Phillip Called Orders For General Spivey.

7 number of cells in their bodies.
Domains Archaea Eukarya Bacteria Ancient Found in Extreme Environments Unicellular Prokaryotes/no nucleus Found everywhere Autotrophs & Heterotrophs Prokaryotes---lack nucleus Found Everywhere Autotrophs & Heterotrophs Eukaryotes---Nucleus Placed into domains and kingdoms based on cell type, ability to make food, number of cells in their bodies.

8 Dense area in a cell that contains nucleic acids---chemical instructions that direct cell’s activities Nucleus Dense area in cell containing nucleic acids---Chemical instructions that directs cells activities. Prokaryotes---cells with no nucleus Eukaryotes---Cells with Nucleus YOU

9 Domain Eukarya Fungi Plants Animals Protists
Eukaryotic organism---cannot be classified as animal, plant or fungus---most unicellular---few multicellular—some autotrophs other heterotrophs. Protists Fungi Multicellular eukaryotes. All heterotrophs Plants Multicellular eukaryotes—most live on land----autotrophs---provide food for heterotrophs Animals Multicellular eukaryotes—live everywhere---hetertrophs

10 What is your scientific Name?
