1 1 Classification copyright cmassengale

2 2 There are 13 billion known species of organisms There are 13 billion known species of organisms This is only_______of all organisms that ever lived!!!!! This is only_______of all organisms that ever lived!!!!! New organisms are still being found and identified New organisms are still being found and identified Species of Organisms copyright cmassengale

3 Classification Using Cladograms ___________ ___________ : A diagram that shows the evolutionary relationships among a group of organisms.

4 4 Cladogram Diagram showing how organisms are related based on shared, derived characteristics such as feathers, hair, or scales copyright cmassengale

5 5 Primate Cladogram copyright cmassengale

6 6 What is Classification? ____________arrangement of organisms into groups based on their similarities ___________: science of classification Taxonomists: scientists that identify & name organisms copyright cmassengale

7 7 Benefits of Classifying Accurately & uniformly names organisms Accurately & uniformly names organisms Prevents ________: wrong name Prevents ________: wrong name – Sea horse, jellyfish, koala bear Uses same language (Latin or some Greek) for all names Uses same language (Latin or some Greek) for all names Seahorse?? copyright cmassengale

8 8 Confusion in Using Different Languages for Names copyright cmassengale

9 9 Latin Names are Understood by all Taxonomists copyright cmassengale

10 10 Carolus Linnaeus 1707 – 1778 Father of ___________ Classified organisms by structure Developed 2- word naming system we use today copyright cmassengale

11 11 Standardized Naming ______________ nomenclature used ______________ nomenclature used Genus species Genus species Latin or Greek Latin or Greek Italicized in print Italicized in print Capitalize genus, but NOT species Capitalize genus, but NOT species Turdus migratorius American Robin copyright cmassengale

18 18 ARCHAEBACTERIA Probably the 1 st cells to ______ __________________-Autotrophs Live in _________ environments Found in: – Sewage Treatment Plants – Thermal or Volcanic Vents – Hot Springs or Geysers that are acid – Very salty water (Dead Sea; Great Salt Lake) copyright cmassengale

19 19 ARCHAEABACTERIA copyright cmassengale

20 20 EUBACTERIA Unicellular-Autotrophs Some may cause __________ Found in ALL HABITATS _____ harsh ones Important decomposers for environment Commercially important in making cottage cheese, yogurt, buttermilk, etc. copyright cmassengale

21 21 Eubacteria- Live in the intestines of animals copyright cmassengale

22 22 Protista Most are _____ellular Most are _____ellular Some are ________cellular Some are ________cellular Some are _______trophic, while others are _________trophic Some are _______trophic, while others are _________trophic Aquatic Aquatic Ex: algae Ex: algae copyright cmassengale

23 23 Fungi Multicellular, except yeast Multicellular, except yeast Absorptive heterotrophs (digest food outside their body & then absorb it) Absorptive heterotrophs (digest food outside their body & then absorb it) copyright cmassengale

24 24 Plantae Multicellular Multicellular Autotrophic Autotrophic Absorb_______to make glucose – Photosynthesis Absorb_______to make glucose – Photosynthesis Cell walls made of _____________ Cell walls made of _____________ copyright cmassengale

25 25 Animalia ______cellular ______cellular Ingestive heterotrophs (consume food & digest it inside their bodies) Ingestive heterotrophs (consume food & digest it inside their bodies) Feed on plants or animals Feed on plants or animals copyright cmassengale

27 27 ______________Keying Used to identify organisms Used to identify organisms Characteristics given in pairs Characteristics given in pairs Read both characteristics and either go to another set of characteristics OR identify the organism Read both characteristics and either go to another set of characteristics OR identify the organism copyright cmassengale

28 28 Example of Dichotomous Key 1a Tentacles present – Go to 2 1b Tentacles absent – Go to 3 2a Eight Tentacles – Octopus 2b More than 8 tentacles – 3 3a Tentacles hang down – go to 4 3b Tentacles upright–Sea Anemone 4a Balloon-shaped body–Jellyfish 4b Body NOT balloon-shaped - 5 copyright cmassengale
