| Question | Answer |
|---|---|
| Opisthokonts | animals(metazoa), true fungi(eumycota), and microsporidia |
| Fungi | Opisthokonts, specifically eumycota, unicellular or multicellular, absorptive nutrition and chitin cell wall, four divisions: Chytridiomycota, Zygomycota, Basidiomycota, Ascomycota |
| Chytridiomycota | Fungal Phylum with flaggelated zoospores, deepest branching clade. ex: Neocallimastix(bovine rumens), Batachochytrium(animal pathogen) |
| Zygomycota | Fungal phylum with nonmotile spores, sporangium bears spores. ex: Rhizopus(bread mold), Mucor(soil mold), Glomus(mutualistic with plants) |
| Ascomycota | Fungal phylum with nonmotile ascospores that are held on asci ex: Neurospora(bread mold), Morels and Truffels, Aspergillus(skin disease), Pneumocystis jirovecii(pneumonia) |
| Basidiomycota | Fungal phylum containing True mushrooms (large fruiting bodies) ex: Amanita phalloides (poison mushrooms), portabello mushrooms |
| Microsporidia | phylum of fungal parasites, small genome & degenerate genes, nonfunctional mito, Encephalitozoon intestinalis, opportunistic pathogen (aids) |
| Viridiplantae | phylum containing plants and algae, primary (red and green algae) and secondary symbionts (Cryptophyte algae, Crysophytes(kelps & diatoms) |
| Primary endosymbionts | Viridiplantae, contains endosymbiotic cyanobacteria and are represented by red (rhodophyte) and green (chlorophyte) algae |
| Green Algae | primary symbiotic algae of the viridiplantae phylum containing chlamydomonas(paired front flagella), Spirogyra, Volvox, Ulva, and Cymopolia |
| Red Algae | Viridiplantae, red from phycoerythrin, deeper waters scavenging light, agar (sulfated polygalactans), porphyra(seaweed) |
| Secondary endosymbionts | second engulfing of primaries, nucleomorph, Cryptophyte and Crysophyte (kelp & diatom) |
| Diatom | Bacillariophyceae, unicellular algae with SiO2 frustules, divide into smaller fragments |
| Coccolithophore | algae with a CaCO3 shell |
| Brown algae | phaeophyceae, aka kelp, leucocin |
| Protists | Amoebas, Ciliates, Alveolates, Heterokonts |
| Amoeba | amorphous with pseudopods, Amoebazoa, Radiolarins(silica), Foraminiferans(CaCO3) |
| Alveolates | Ciliates, Dinoflagellates, apicomplexans |
| Ciliates | many cilia, for engulfing and taxis, paramecium has oral groove, and digestive and contractile vacuoles |
| Dinoflagellates | phytoplankton, two flagella (one around shell), chloroplast surrounded by 3 membranes, red from carotenoid, red bloom |
| Apicomplexes | parasites, plasmodium, malaria, apical complex allows entry to host cell, invades liver, merozoites in RBC, replicate in mosquito |
| Trypanosomes | obligate parasites two examples Leishmania major (leishmaniasis) and Trypanosoma brucei (ASS) |
| Metamonads | parasites and symbionts, no mitochondria, Giardia lamblia is an example |
| Choanoflagellates | Closest relative to metazoans, collar resembles sponges, may be missing link between animals and fungi |
| Amanita phalloides | toxic mushroom, alpha amanitin inhibits rnapol II |
