Title: Classifying Organisms
1Classifying Organisms
Easier to Study!
Classification
The process of grouping thing based on
similarities.
Taxonomy
The scientific study of how living things are
classified
2Carolus Linnaeus (Carl von Linné)
Naming Systems
Carolus Linnaeus
1707-1778 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
3Binomial 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.
4Genus
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.
5Most biologists classify organisms into 8
levels.
Broad to Specific
More levels share more have in common

7Domains
Eukarya
Archaea
Bacteria
Ancient Found in Extreme Environments Unicellular
Prokaryotes/no nucleus
Found everywhere Autotrophs Heterotrophs Prokary
otes---lack nucleus
Found Everywhere Autotrophs Heterotrophs Eukaryo
tes---Nucleus
Placed into domains and kingdoms based on cell
type, ability to make food, number of cells in
their bodies.
8Dense area in a cell that contains nucleic
acids---chemical instructions that direct cells
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
9Domain Eukarya
Eukaryotic organism---cannot be classified as
animal, plant or fungus---most unicellular---few
multicellularsome autotrophs other heterotrophs.
Protists
Fungi
Multicellular eukaryotes. All heterotrophs
Plants
Multicellular eukaryotesmost live on
land----autotrophs---provide food for heterotrophs
Animals
Multicellular eukaryoteslive everywhere---hetertr
ophs
