Bacteria, Protists, Fungi Domain Bacteria – unicellular prokaryotes Domain Archaea – unicellular prokaryotes Bacteria Cyanobacteria Includes “extremophiles” We won’t be looking at any of these in this lab 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 We won’t be using oil immersion lens in this lab This is what bacteria looks like growing in culture, you have to look at it under the microscope to see individual cells Gleocapsa Oscillatoria Anabaena Domain Eukarya Includes all organisms made of eukaryotic cells Includes: Protists Fungi Plants Animals As discussed in lecture, the phylogeny and taxonomy are changing and moving away from the 5 Kingdom system as better molecular techniques allow us to relook at the relationships of organisms Common names • • “Protozoa” – heterotrophic, “animal-like” “Algae” – autotrophic • • Groups: • • • • • • • Microscopic – phytoplankton Macroscopic - seaweed 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 Trypanosoma Trichomonas Plasmodium – no means of locomotion Look for it inside red blood cell Microscopic algae Phytoplankton Macroscopic algae “seaweed” Green Algae Euglena – photosynthetic flagellate, can also be heterotrophic 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 The Fungi Heterotrophic organisms that produce windblown spores both sexually and asexually Spores develop into a mycelium (collection of haploid spores called hyphae) Sexual reproduction Hyphae from 2 different individuals meet up to fuse and form a diploid nucleus That diploid nucleus undergoes meiosis to produce spores Phylum Ascomycota Phylum Basidiomycota What we think of when we say “mushrooms” 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 #)
