Show Answers:

  1. Eukaryotes cause __?__ infections.
  2. What are the 4 types of parasitic infections caused by Eukaryotes?
    • Chronic
    • Complex-Life cycle
    • Multiple life stage
    • Multiple hosts
  3. What are the 5 main phylogenies of Eukarya?
    • Primary Algae and Green plants
    • Protists
    • Fungi and Animals
  4. What broad group of Eukarya do Fungi and Animals fall belong in and why?
    • Opisthokonts
    • Common insertions/deletions in key genes
    • single flagellum (unlike protists which are paired)
  5. What broad phylogenic group do Algae and Plants fall under? (add to this card slide 8)
  6. What are unique characteristics of Fungi (2)
    • Cell wall made of chitin ( acetylated polysaccharide + stops psuedopods)
    • Grow at Hyphal tips (branches are mycelia)
  7. What are yeast and what make them unique (3)?
    • Fungi
    • Reproduce via budding
    • Asexual (mitosis in 1n and 2n) and sexual reproduction
  8. What is Ascomycetes and its 4 uses?
    • Fungi
    • Antibiotic source (penicillin)
    • cooking
    • Eating
    • Disease
  9. What are Basidiomycetes and what 4 characteristics make them unique?
    • Fungi - Mushroom
    • Gametes fuse, not nuclei
    • Fruiting bodies
    • Nuclei form in basidium
    • Meiosis to form basidiospore
  10. What is Chlorophyta?
    Green algae (Chlorophyll a)
  11. What is Rhodophyta and 3 characteristics?
    • Red Algae
    • Unicellular filaments
    • Phycoerythrin (allows growth in deeper water, absorbs lower energy light)
  12. What are secondary endosymbionts and an example?
    • Algae engulfed by a protist
    • Diatoms (SiO2 - quartz shell)
  13. What is brown algae and what gives it brown color?
    • Kelp (protist, secondary endosymbiont)
    • energy storage lipid
  14. What forms amorphous shapes and slime molds?
  15. What are Cecozoa and examples?
    • Shelled Amoebas (Marine habitat)
    • ex - Radiolarians - Amoebas with filamentous pseudopods stabalized by mictotubules
  16. What are Alveolates and distinct characteristics?
    • Ciliates
    • Have cilia and multiple copies of nuclear DNA (Macronucleus) (original nucleus in micronucleus)
  17. What are Apicomplexans and distinct characteristics?
    • Alveolates
    • Apical complex invades host
    • No cilia
    • obligate parasites
  18. Where is the apicoplast derived from and in what group is it found?
    • Chloroplast
    • Alveolate apicomplexans
  19. What is a cryptophyte? What group is it not part of and why?
    Protist that engulfed an Algae. They contain a nucleomorph which is the vestigal nucleaus of the algae. It is not part of viridiplanae because it is a protist.
  20. What is a filamentous algae called?
  21. What is an individual algae cell called?
  22. What is a sheet of algae called?
  23. What is a colony of algae called?
  24. What is another name for cryptophytes?
    Secondary endosymbionts
