| Question | Answer |
|---|---|
| Major char. of Diplomonads and Parabasalids | lack plasmids and have modified mitochondria. many live in aerobic environments |
| Phylum Diplomonads | -parasitic in mammals -unicellular -anaerobic -modified mitochondria called mitosomes -2 nuclei -multiple flagella |
| Phylum Parabasalids | -parasitic -unicellular -anaerobic -undulating membrane |
| major charact. Phylum Euglenazoa | -predator -heterotrophic -photosyntethic autotrophs -parasites -unique flagellar structure |
| Subphylum Kinetoplastids | -heterotrophic or parasitic -unicellular -fressh water -marine -moist (aquatic) -one big mitochondria -Phyum Euglenazoa |
| Subphylum Euglenids | -mixo/auto/hetero -unicellular -freshwater mostly (aquatic) -exhibit mitosis -2 flagella short + long |
| Character. of Clade Alveolates | membrane bound sacs (alveoli) under plasma membrane |
| Phylum Dinoflagellates | -Clade Alveolates -photosynthetic, mixotrophic, half are heterotrophic -unicellular/colonial -cellulose plates (cell wall) -marine, freshwater (aquatic) -red tides -two flagella -major photosynthesizers |
| Phylum Apicomplexans | -Clade Alveolates -parasites -unicellular -parasite in host -have apical complex specialized for penetrating host cells |
| Phylum Ciliates | -Clade Alveolates -hetero -unicellular -fresh water -move using cilia -2 types of nuclei -gas exchange |
| Char. Clade Stramenophiles | - two flagella: one hairy, one whiplike |
