  15. diatoms amoebozoans red algae ciliates water molds(oomycetes) You are given an unknown organism to identify.It is unicellular and heterotrophic. It is motile, with well-developed organelles and two nuclei, one large and one small. You conclude that this organism is most likely a member of which major group?

  40. 28.3A phylogenetic hypothesis of eukaryotes(see book page 578)

  41. 28.24. Plasmodial slime mold

  42. 28.24. The life cycle of a plasmodial slime mold, such as Physarum

  43. Slime mold Sporangia

  44. 28.25 The life cycle of a cellular slime mold (Dictyostelium)

  45. Dictyostelium life cycle

  46. 28.27. Protists play key roles in ecological relationships (and in public health) Protists are key producers in aquatic communities. Up to 25% of the world’s photosynthesis is performed by protists. Organisms in aquatic communities depend on photosynthetic protists for food

  47. 28.7. Protists play key roles in ecological relationships (and in public health) High water temperatures (global warming) and pollution cause corals to expel their symbiotic dinoflagellate protists This results in coral bleaching and, eventually coral death
