Early Eukaryotes Kingdom Protista –Most diverse Kingdom Polyphyletic Should be split into multiple Kingdoms Many have sexual reproduction Autotrophs and heterotrophs
Archaezoa Do not have mitochondria Similar to first Eukaryotes Example – Giardia
Rhizopoda Amoeba Move and feed by extending cytoplasmic projections –Pseudopods Heterotrophs
Actinopoda Thin pseudopods –Pseudopods controlled and supported by microtubules Exoskeletons made of silica Heterotrophs
Euglenophyta Two flagella emerge from a pocket Some are both autotrophic and heterotrophic Example – Euglena
Ciliophora Cilia for movement and food gathering Paramecium, Stentor, Vorticella Some has sexual reproduction – Conjugation
Stramenopila Hair-like projection off flagella Often contain unusual chloroplasts Many are heterotrophs Examples –Diatoms – aquatic autotrophs –Water molds
Rhodophyta Alternation of generation (sexual reproduction) –Gametes do not have flagella Example –Red Algae
Chlorophyta Green algae Alternation of generation (sexual reproduction) –Gametes have flagella Can form large colonies
Slime molds Spores form amoeba-like cells Amoeba feed until food runs out Amoeba congregate and form multicellular “slug” “Slug” differentiates into fruiting body (sorocarp) Sorocarp forms spores
