1 ClassificationS7L1a: Students will be able to compare organisms by similar and dissimilar characteristics.S7L1b: Students will be able to classify organisms into the six kingdoms based upon these characteristics.
2 Characteristics of Living Things All have cellsAll have chemicals needed for lifeAll respond to stimuliAll use energyAll grow and developAll reproduce
3 Cell Theory All organisms are made of one or more cells The cell is the basic unit of all living thingsAll cells come from other cells
4 Tools Scientists Use to Classify Organisms Branching DiagramsDichotomous KeyEight-Level SystemBinomial Nomenclature
5 Branching Diagrams – show the evolutionary relationships amongst organisms.
6 Dichotomous Key – a tool used to identify organisms and consists of the answers to a series of questions.The questions are asked in pairs, and the answers are in yes or no format.
7 Eight-Level System – organisms are placed in categories from least similar to most similar based upon shared characteristicsDomainKingdomPhylumClassOrderFamilyGenusSpecies
8 Binomial Nomenclature – a two-part scientific name Scientific Name = Genus + speciesGenus name is capitalized or can be abbreviatedSpecies name is lower caseExample: Homo + sapiensHomo = Genussapiens = speciesScientific name is Homo sapiens, which means “knowing man”
9 Three Domains and Six Kingdoms BacteriaEubacteriaEukaryaProtistaFungiPlantaeAnimaliaArchaeaArchaebacteria
10 Classification into Domains and Kingdoms Organisms are classified into Domains and Kingdoms based upon the following three characteristics:Cell typeHow they get their foodNumber of cells inside their body
11 Two Cell Types Prokaryotes Eukaryotes Single-celled organisms (unicellular)They do not have a true nucleusDo not have membrane-bound organellesEx: Archaea and BacteriaEukaryotesMultiple-celled organisms (multicellular)Have a nucleusHave membrane-bound organellesEx: Humans, Protists, Plants, and Yeasts
12 Domain Archaea Kingdom – Archaebacteria Characteristics: Prokaryotes –single-celled organismsDo not have a nucleusLive in extreme environments
13 Domain Bacteria Kingdom – Eubacteria Characteristics: Prokaryotes –single-celled organismsDo not have a nucleusLive in the soil, water, on and inside the human bodySome cause disease, while others help fight disease-causing bacteria
14 Domain Eukarya Kingdoms: Protista, Fungi, Plantae, and Animalia Characteristics:Have a nucleusMembrane bound organellesProtozoans Fungi Plantea Animalia
