  1. The Eukaryotes 12a: Protozoans

  2. Eukaryotes in general cells chromosomes made of chromatin cell division: mitosis & cytokinesis (if) sexual reproduction meiosis fertilization

  4. Kingdom Protista highly diverse; may be more than 1 mostly unicellular 2 “lifestyles” photoautotrophic: algae chemohetero & often mobile: protozoa

  5. Protozoa nutrition trophozoite vs. cyst “free-living” vs. parasite Protozoa locomotion cilia/flagella/amoeboid flow by vector Protozoa life cycle & reproduction asexual: fission, budding, coenocyte, schizogony

  6. coenocyte budding schizogony

  7. Protozoa nutrition trophozoite vs. cyst “free-living” vs. parasite Protozoa locomotion cilia/flagella/amoeboid flow by vector Protozoa life cycle & reproduction asexual: fission, budding, coenocyte, schizogony sexual: gametes, zygote Protozoa habitat
