Document Summary
Protists are a grade rather than a clade. Endosymbiosis: origin of life, how chloroplasts and mitochondria are acquired. Nucleomorph: remnant od eukaryote genome within 3rd membrane. 6 major clades: excavata flagellated parasites two main groups. Diplomonads + parabasalids: have reduced mitochondria, anaerobic, generally parasites. Grouped together based upon shared presence pf alveoli beneath the cell membrane; three distince lineages. Ciliates: cell coveed in many short cilia rather than few long flagella. Rhiziaria; group of amoebas pseudopodia; cytoplasmic streaming for locomotion, prey capture, etc. foraminiferans: shell of calcium carbonate. Chlorarachniophytes; mixotrophic group secondary endosynbiois with green alae. Archaeplastida; multicellular with photpigment that makes them red. Unikonta: fungi and animals two major groups baed upon general dna and myosin. Amoebozoans; slime molds and other amoebas locomotion via psuedoodia. Opisthokonts unicellular and multicellular flagella. know chcarcateristics of each clade. Dinflagelletes cause neurotoxic shellfish poisoning otherwise known as crimson tide. Diatoms; photosynthetic algae with silica wall around cell (glass)
