Kingdom Protista Calibration of Ocular Micrometer Survey of The Environment - Collect Specimens Microscope Quiz 2 Lab Video - Kingdom Protista Protista Video #1 - Microscopic Pond Life https://www.youtube.com/watch?v=PPls7CQxOBA Protista Video #2 - Amoeba https://www.youtube.com/watch?v=4XlzCe5gDu0 3 Kingdom Protista Members divided into: Free-living microbes (cause no disease) vs parasitic microbes (cause disease) Simplest Eukaryotes Domain Eukarya Mostly unicellular (some multicellular) Originally thought to be Prokaryotes (Kingdom Monera)  are NOT! Very diverse group of microbes 4 Subkingdoms Classified into Subkingdoms: (subkingdom is not a taxon, just like subspecies isn’t either) 1. Subkingdom Protozoa (animal-like) 2. Subkingdom Algae (plant-like) 3. Subkingdom Slime Molds (fungus-like) S. k. Protozoa S. k. Algae S. k. Slime Molds Motile Phyla classification Photoautotrophs Division classification Are NOT fungi! (based on locomotion) (based on photosynthetic pigment) Are NOT animals! Are NOT plants! 5 Subkingdom Protozoa Phylum Specialized Structure for Locomotion/Movement Function/Miscellaneous Function - for movement & phagocytosis Pseudopodia = “false feet,” extension of cytoplasm Ex - Amoebas Function - for movement Sarcodina Pseudopodia Mastigophora Flagella Ciliophora Cilia Function - can create water vortex, suction for feeding Apicocomplexa Adhesions Function - gliding movement Adhesions = surface structures 6 Phylum Sarcodina - Amoeba 7 Subkingdom Algae Division Alternate Name Misc. Freshwater algae Ex - Euglena Euglenophyta Chlorophyta Green Algae Freshwater algae Chlorophyll (green)pigment Chrysophyta Golden Algae Freshwater algae Ex - Diatoms Phaeophyta Brown Algae Marine algae Ex - Kelp forest in ocean Rhodophyta Red Algae Marine algae In deeper ocean layers 8 Division Cyanobacteria “Cyano” - “blue/purple” Formerly known as Blue-Green Algae Use to be classified into Kingdom Protista (Subkingdom Algae) but are NOT! Are Prokaryotes (bacteria)  now classified into Kingdom Monera Simplest photosynthetic organisms Major producers of oxygen 9 10 11
