  1. what does eukaryotic mean?
    the cell contains a nucleus
  2. how is fungi different than other plants?
    fungi don't make their own food, they get it from other organisms
  3. how are fungi cells different than animal cell
    fungi cells contain cell walls
  4. does fungi include yeast and mold?
    yes fungi include some yeast and mold
  5. true or false? mold is typically a multi-cellular organism
  6. how does fungi, mold and yeast reproduce?
    by sexual and asexual spores
  7. ?how does yeast reproduce
    asexually by budding
  8. true or false? protozoa are single celled eurokyotes?
  9. true or false protozoa are similar to animal cells in their nutritional needs?
  10. what are the 3 types of locomotion?
    • Pseudopodia
    • Cilia
    • Flagella
  11. define pseudopodia
    pseudopodia are extentions that flow in the direction of travel
  12. define cilia
    cilia are short numerous protrusions that vibrate to propel the protozoa
  13. define flagella
    flagella are long extensions, few in number and longer than cilia
  14. how does protozoa reproduce?
  15. where do protozoa typically live?
    in fresh water but can live in animals where they cause disease
  16. what are algae?
    uni and multicellular photosynthetic organisms
  17. how do Algae obtain their nutrients?
    by photosynthesis, they make their own food
  18. what are some examples of Algae?
    seaweed and kelp
  19. where can one expect to find Algae?
    in freshwater ponds, streams, lakes and oceans
  20. what does prokaryotic mean?
    organism lacks nuclei
  21. what are the bacteria cell wall composed of?
    cell wall is composed of a polysaccharide called Peptidoglycan
  22. do Archaea have Peptidoglycan walls?
    no, instead their wall is composed of other polymers
  23. does bacteria and Argae reproduce asexually?
  24. are bacteria and argae smaller than eurokyotic cells?
    yes, they are smaller than eurokyotic cells
  25. true or false?
    Archaea are often isolated from extreme environments such as highly saline mono late in california, acidic hot spring and oxygen depleted mud?
  26. true or false?
    Archaea is known to cause disease?
    false, they have not been known to cause disease
  27. a few bacteria produce disease because they derive their food from the host and produce toxic waste. On the other hand Algae do not cause disease, why not?
    because they produce their own food via photosynthesis
