  1. what is it called when a diploid, multi-cellular, spore producing organism (sporophyte) alternates with a haploid, multicellular. gamete-producing organism (gametophyte)
    Alternation of generation
  2. what is a haploid organism that produces haploid spores
    sporophyte
  3. same form (gameteophyte and sporophyte) look alike
    isomorphic
  4. gameteophyte and sporophyte look different
    heteromorphic
  5. sexual process involving exchange of genetic material without reproduction; carried out by paramecium
    conjugation
  6. what organism has 2 different types of nuclei
    paramecium
  7. which nuclei controls everything that happens in a cell?
    macronucleus
  8. which nuclei can be in multiples and be involved in conjugation
    Micronuclei
  9. 5 cilliates that protists are divided into which are related to each other
    chromalveolates, plantae, excavates, rhizaria, unikonts
  10. what is different about each group of cilliates?
    they each have different rRNA
  11. what has membrane bound sacs (alveolates) located just underneath the plasma membrane?
    alveolates
  12. what are the characteristics of a dinoflagellate?
    unicellular, biflagellate, mostly marine and photosynthetic, alveoli often form armored plates made of cellulose, bioluminescent, some are endosymbiotic with coral and giant arms.

  14. what possesses cillia, is heterotropic (most), has trichocysts, possesses 2 types of nuclei
    Cilliates
  15. what are unicellular flagellates?
    excavates
  16. name 3 types of excavates
    diplomads, parabasalids, and euglineds
  17. what has multiple flagella, 2 nuclei, reduced mitochondria, and are parasitic
    diplomonads
  18. what is an example of diplomonads that contaminates water and causes travelers diarrhea
    Giardia Lambia
  19. what have multiple flagella, reduced mitochondria, symbiotic relationships with incects and animals, and undulating membrane (some)
    parabasalids
  20. what is an example of a parabasalid that is an STD?
    trichomas vaginalis
  21. what is biflagellate, has a pellicle composed of protein strips, and food stored as paramylon (polysaccharides)
    euglenids
