  1. eukaryotes differ from prokaryotes because
    • they are larger
    • contain a nucleus
    • mitosis or meiosis
    • organelles
  2. what regulates traffic into and out of the nucleus
    nuclear pores
  3. nucleolus is
    where the rRNA synthesis occurs
  4. what kind of layer does nucleus have
    double lipid bylayer
  5. haploid
    single set of chromosomes
  6. diploid 
    having two sets of chromosomes
  7. histones are 
    proteins where DNA is condensed on
  8. endoplasmic reticulum two types
    • smooth - lipid metabolism, detox reactions
    • rough - ribosomes docked, protein synthesis
  9. mitochondria
    • powerhouse
    • site of respiration
    • has its own genetic material
  10. bacterial endosymbiotic theory
    certain organelles originated as free-living bacteria that were taken inside another cell as endosymbionts
  11. mitochodria developed from
    proteobacteria in particular Rickettsiales
  12. chloroplasts developed from
  13. chloroplasts

    • does not spin
  19. eukaryote capsule
    • glycocalyx 
    • similar to prokaryotes
  20. characteristics of fungi

    • ergosterol in membrane
    • chitin in cell walls
  21. yeast are what
    single celled forms of fungi
  22. mycelium
    • vegetative part of a fungus
    • formed from hyphae
  23. what holds chromosomes together
  24. how many chromosomes do we have 
    23 pairs  = 46
  25. if two subunits of ribosomes with 40s and 60s would they have a total size of 100s
    • no
    • total size of 80s
  26. actin is
    • micro tubule
    • protein filament found in cytoskeleton
  27. hyphae form...
    mycelium (colony)
  28. are fungi photosynthetic?

    active feeding stage of a protist
  37. protist dormant stage =
  38. 4 classifications of protists
    • sarcodina (amoebas)
    • mastigophora (have flagella)
    • ciliophora (cilated)
    • apicomlexa (sporozoa)
