  2. Features of Unikonta • Animals, plants, some fungi • BIGGEST group! • Most free-living, some parasitic • Amoebozoans: • Lobe or tube shaped pseudopodia • Move by the means of internal cytoplasmic flow • Common in soils and aquatic habitats • Do not form microtubule-supported structures except during mitosis • Opisthokonts: • A single posterior flagellum • Highly variable

  3. Common Species of Unikonta • Amoebozoans- Amoeba, Slime Mold, Gymnamoeba, Entamoeba • Opisthokonts- nucleariids, choanoflagellates, animals, fungai • Plasmodial “sporangia” (slime mold) forms a plasmodium mass • Act as decomposers, engulfing food by phagocytosis • Entamoebahistolytica causes amebic dysentery in humans • Infection of the intestines

  4. Ecological & Evolutionary Significance • May have been the first group of Eukaryotes to diverge from other Eukaryotes, not widely accepted
