  1. general characteristics of protozoa
    • eukaryotic
    • unicellular
    • live alone or in a colony
    • contains appendages for movement (flagella, cilia)
  2. what are the 4 classes of protozoa
    • sarcodina
    • mastigophora "flagelleta"
    • ciliophora
    • sporozoa
  3. general characteristics of sarcodina?
    • pseudopodia: for movement and catching food
    • amoebas
  4. general characteristics of mastigophora "flagellata"
    • can have 1 or more flagella
    • flagella: for movement and catching food
    • flagella originates from blephoroplast/kenitoplast
    • body is divided into extoplast/endoplast
  5. general characteristics of ciliophora
    • cilia: shorter, more numerous, and thicker than flagella
    • each cilia originates from kinectosome (found in ectoplast)
    • rhythmic movement of cilia damages cell
  6. general characteristics of sporozoa
    • no locomotive organelle
    • free living
    • all parasitic
  7. describe the phylum platyhelminthes
    • flatworms
    • multicellular eukaryote
    • acoelomite: no body cavity
    • majority are hermaphrodites (monoecious)
    • some are dioecious
    • contains a sucker, mouth, ventral sucker (acetabulum)
  8. what are the classes of platyhelminthes
    • trematoda: flukes
    • cestoda: tapeworm
  9. describe trematoda
    • "flukes"
    • some monoecious/dioecious
    • primitive digestive system
    • contains posterior and anterior sucker
    • monogenetic flukes
    • digenetic flukes
  10. describe the difference between monogenetic flukes and digenetic flukes
    • monogenetic flukes: cannot be found in human. Only in lower animals. Ex) frog
    • digenetic flukes: complex life cycle. Requires more than one intermediate host. Found in high animals (human). Found in 4 groups (intestinal, blood, liver, lung)
  11. what are the 5 life stages of flukes in order from young to mature
    • meracelium
    • sporocyst
    • radia
    • cercaria
    • metacercaria
  12. describe cestoda
    • "tapeworm"
    • longer than flukes
    • segmented
    • each segment is monoecious
    • contains head (scolex), sucker (hooks), neck
  13. describe aschelminthes
    • "roundworms" "nematyleminthes"
    • all dioecious
    • females are longer
    • males are shorter, thinnger
    • only class that can harm humans (nematodas)
    • different groups (intestinal, tissue, blood)
    • contains spicule (penis) and vagina
  14. describe acanthocephala
    • "thorny headed worm"
    • small, dioecious
    • no digestie system
    • need intermediate host (cockroach, beetle, insects)
    • pseudo coelomate "false body cavity"
    • contains probascus
  15. describe arthropoda
    segmented organism, some have wings, some don't
  16. what are the 5 classes of arthropoda and name examples
    • crustacea: shrimp, crab, lobster
    • chilopoda: centipeds
    • arachnida: body contains cephalothorax and abdomen, scorpion, ticks
    • pentastomida: tongue worm, not present in humans 
    • insecta: body composed of head, thorax, abdomen. Fly, lice, mosquito
