Description
EUKARYOTES – PROTISTA Reproduction: Mitosis, spore formation, asexually & sexually Energy: Autotrophic or Heterotrophic Mobility: Sessile or Motile Cell orginization: Single celled Animal-like Protists:  Protozoa  Characterized mostly by its method of locomotion (Ability to move from one place to another )  Hetertrophs – scaveners, predators, parasites  Most reproduce by mitosis, some sexual reproduction  Sprozoans – parasites that produce spores Example: Prarmecium ( use cilia to move and sweep food ), Euglena ( Use flagella to move and hunt ), Amoeba (movement with pseudopodia) Plant-like Protists:  Phytoplankton, aquatic  Has chlorophyll but lack true plant like organs  Autotrophs  Usually sessile  Classified based on chloroplasts and pigment Example: Green algae, Brown algae, Red algae Fungi-like Protists:  Fungus like but also has charateristics of protoza and plants  Produces spores  Motile  Heterotrophs – decomposers Example: Moulds and mildews EUKARYOTES – ANIMILIA Reproduction: Sexually – meiosis Energy: Heterotrophic – digest food Mobility: Motile Cell orginization: Multicellular no cell walls Characteristics: All animals share the following characteristics:  They are eukaryotic, multicellular and have no cell walls  The are heterotrophs that usually ingest and then digest their food 
