+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

+Common Species of Unikonta Amoebozoans- Amoeba, Slime Mold, Gymnamoeba,

Opisthokonts- nucleariids, choanoflagellates, animals, fungai

Plasmodial “sporangia” (slime mold) forms a plasmodium mass Act as decomposers, engulfing food by phagocytosis
