2 ____________ the science of naming and classifying organisms ____________: evolutionary history ____________: the science of classification based on evolutionary history of organisms Taxonomy: Vocabulary to know Phylogeny Systematics Designed by Pyeongsug Kim, ©2010 www.science-i.comwww.science-i.com

3 Designed by Pyeongsug Kim, ©2010 www.science-i.comwww.science-i.com Organisms -any living things -animal, plant, fungus, or microbes (protozoa, bacteria, archea..) - Can be classified by Hierarchical classification Picture from http://www.flatrock.org.nz/topics/animals/are_animals_conscious.htm http://girltears.files.wordpress.com/2008/05/diatom-shapes-527153-ga.jpg http://snarkerati.com/movie-news/why-the-3d-bible-movie-annoys-me/http://www.flatrock.org.nz/topics/animals/are_animals_conscious.htmhttp://girltears.files.wordpress.com/2008/05/diatom-shapes-527153-ga.jpg http://snarkerati.com/movie-news/why-the-3d-bible-movie-annoys-me/

4 Designed by Pyeongsug Kim, ©2010 www.science-i.comwww.science-i.com Organism classification - Hierarchical classification :based on some hierarchical structure -Three major Domains of life -Kingdom, Phylum, Class, Order, Family, Genus and species *Hierarchy the arrangement of a particular set of ranks or levels.

5 Designed by Pyeongsug Kim, ©2010 www.science-i.comwww.science-i.com All living things All living things (including microbes) are classified into …. ___ Domains and ___ Kingdoms 36

7 Biological classification Domains and kingdoms- the biggest groups Taxonomy- the science of classification From Dr. Wright’s Bio42 class

8 “Scientific name!” (Binomial name) 3 Domains - __________________________ 6 Kingdoms ______________________________ Eubacteria, Archaea, & Eukarya Eubacteria, Archaea Plantae, Animalia, Fungi, Protista “Domain, King Philps“ Came Over For Grape Soda.” Designed by Pyeongsug Kim, ©2010 www.science-i.comwww.science-i.com

10 Domain Archaea Eubacteria Fungi Plantae Protista Animalia Kingdom Archaea Eubacteria Eukarya Genus (common name) Archaea Bacteria Cyanobacteria H.plyori, E.Coli Oscillatoria, Gram+,- Fungi, Mold Mushrooms Yeast, Penicillium, Rhizopus, Aspergillus….. Moss, flowering plant Pinus, sun flower,….. Algae Protoza Volvox, diatoms,….. Euglena, paramecium…. Vertebrates invertebrates sponges, helminths (worms) Prokaryotes Eukaryotes Designed by Pyeongsug Kim, ©2010 www.science-i.comwww.science-i.com

11 EukaryotesProkaryotes No nucleus DNA in Nucleus 80S ribosomes Cell wall 70S ribosomes Some have cell wall(fungi, plant) Binary fission Non-sexual Mitosis, some do binary fission. Sexual or non-sexual Singcirculr DNA Multiple, linear DNA; histones No membrane-bound organelles membrane-bound organelles Bacteria, Achaea Algae, protozoa, plant, animal, fungi ONLY Unicelluar Uni- or Multicellular Designed by Pyeongsug Kim, ©2010 www.science-i.comwww.science-i.com

YesNo Circular chromosome? Yes No (except in mitochondria and chloroplasts) Histones?NoYes Dr. Wright’s Bio7/27 class slide

13 Bacteria Designed by Pyeongsug Kim, ©2010 www.science-i.comwww.science-i.com -Single cell prokaryotes. -Found everywhere. -Binary fission -Motile(flagella) or non-motile -have various metabolic properties -Peptidoglycan cell wall -No histones -Some cause human diseases. -Lots in human body.

14 Archaea Designed by Pyeongsug Kim, ©2010 www.science-i.comwww.science-i.com -Single cell prokaryotes. -Found everywhere. really like “extreme” environments. extreme temperature, pH, -live in hyperthernal vent, Hot springs.. - have unusual metabolic properties -Cell wall (but not Peptidoglycan) -have histones -Don’t cause disease as known so far. -Methanogens in human body.

They are NOT organisms,(non-living)  termed “agents”  Can’t be classified into any domain or kingdom Virus ______ Nucleic acid (RNA) Plant diseases (as known so far) Viroids ______ Protein Diseases in animals (including humans) “Mad cow disease” Prions
