Bacteria, Protists, Fungi Taxonomy is changing DNA technology is showing relationships previously not known You will hear the term “clade” – what does that mean? Clade – any taxon that consists of all the evolutionary descendants of a common ancestor Identified by picking any point on a phylogenetic tree and tracing all the descendant lineages Binomial Nomenclature, Scientific Name Genus species or Genus species Genus is capitalized, species is lowercase Italicized or underlined Homo sapiens Tursiops truncatus Callinectes sapidus Homo sapiens Tursiops truncatus Callinectes sapidus Domain Bacteria – unicellular prokaryotes Domain Archaea – unicellular prokaryotes Bacteria Cyanobacteria Includes “extremophiles” Domain Eukarya – eukaryotes Kingdom Kingdom Kingdom Kingdom Protista Fungi Plantae Animalia Tips: Start on Scanning objective, look for color Center and focus Move to the 10x objective Center and focus Move to the 40x objective Center and focus If necessary, move to oil immersion Place drop of oil on slide and move oil lens into the oil DO NOT get oil on any of the other lenses Be sure to WIPE oil off of lens when done!!!!! (with lens paper!) Shapes Spirillum Coccus Bacillus Gleocapsa Oscillatoria Anabaena Common name • • Protozoa – heterotrophic, “animal-like” Algae – autotrophic Groups: • • • • • • • Excavata – Giardia, Trichomonas, Euglena, Trypanosoma Alveolates – dinoflagellates, apicomplexans (plasmodium), ciliates (paramecium) Stramenophiles – oomycetes, diatoms, brown algae Rhodophytes – red algae Chlorophytes – green algae Rhizaria – foraminiferans, radiolarians Amoebozoans – plasmodial slime molds, Amoeba Amoeba proteus – move by pseudopodia Radiolarians Globigerina Ciliates Paramecium Stentor Vorticella Trypanosoma Red blood cells Trichomonas Plasmodium – no means of locomotion Look for it inside red blood cell Microscopic algae Phytoplankton Macroscopic algae “seaweed” Green Algae Microscopic Spirogyra Look for green spirals Volvox Macroscopic Euglena – photosynthetic flagellate Look for flagella and chloroplasts, can be mistaken for paramecium Diatoms Electron Microscope picture Dinoflagellates Ceratium Brown Algae Macroscopic examples Sargassum Fucus Red Algae Macroscopic examples Slime Molds Plasmodial slime molds Physarum Phylum Zygomycota – black bread molds Rhizopus – under the microscope Phylum Ascomycota Phylum Ascomycota – under the microscope Saccharomyces - yeast Penicillium Aspergillus Peziza Cross section of cup seen on previous slide Phylum Basidiomycota What we think of when we say “mushrooms” Phylum Basidiomycota – under the microscope Coprina On one side write: Domain Kingdom Group Genus Characteristics Know what is prokaryotic and what is eukaryotic! On the other side: Picture of the organism On Handout Domain is capitalized Group is in bold print Genus is underlined (# is the slide #) microbewiki.kenyon.edu/index.php/Spirillum www.life.umd.edu/CBMG/faculty/asmith/smith2.html commons.wikimedia.org/wiki/File:Bacillus_subt... www.vcbio.science.ru.nl/.../labels/print/PL0013/ botit.botany.wisc.edu/.../Oscillatoria_MC.html fnie-educationalmedia.pbwiki.com/Cyanobacteria faculty.clintoncc.suny.edu/.../protists.htm bio1903.nicerweb.com/.../lab/diversity/protista/ https:/.../qry_media_id.php?media_id=2340 www.mccc.edu/%7Esmithro/Prokaryotes%20and%20P... www.microscopy-uk.org.uk/.../wdstentor2.html http://www.biology-resources.com/drawing-paramecium-vorticella.html io.uwinnipeg.ca/.../16cm05/1116/16protis.htm Noaa.gov www.bioweb.uncc.edu/.../labpics/lab1pics.htm workforce.cup.edu/buckelew/Plasmodium%20vivax... http://www.estrellamountain.edu/faculty/farabee/biobk/aM._conica_tjv.jpg http://www.gltech.org/library/htmlaps/scannell/images/conica.jpg www.plantsci.cam.ac.uk/.../page18/page18.html
