PROTISTA Kingdom, Phylum Example Domain Eukarya Autotrophic by photosynthesis, some heterotrophic by phagocytosis, or both All: Kingdom Protista Animal-like Protists Phylum Protozoa Nutrition & Digestion Heterotrophic (phagocytosis – engulf food) Reproduction & Cell Type Importance Mostly unicellular; multicellular forms: lack tissue organization Cell type: eukaryotic; have nucleus and complex organelles Classified based on what they don’t have. Many different types of movement based on structure of species Reproduction: Asexually (binary fission or multiple fission), sexually (conjugation) Move independently with pseudopodia (cytoplasmic extensions) Unicellular cilia Unicellular Flagella Binary fission and sexual reproduction (conjugation-2 cells join and their macronuclei disintegrate. Meiosis, then mitosis- see text) Unicellular Believed to be the first cells that developed into the more complex cells of organisms in the animal kingdom. Binary fission Amoebas Some parasitic Animal-like Protists Heterotrophic Paramecium Some parasitic Phylum Ciliophora Digestion: oral groove, mouth pore, gullet, anal pore, contractile vacuole Animal-like Protists Heterotrophic and autotrophic Euglena Phylum Sarcomastig o-phora Movement & Body Plan Binary fission Some parasitic Most elaborate organelles of any protist
