Document Summary

Overview: a world in a drop of water. In the past, taxonomists classified all protists in a single kingdom, In ciliates, reproduction and conjugation are separate processes. In a real sense, ciliates have sex without reproduction. Concept 28. 5 stramenopiles have hairy and smooth flagella: the clade stramenopila includes both heterotrophic and photosynthetic protists, the name of this group is derived from the presence of numerous fine, hairlike projections on the flagella. In most cases, a hairy flagellum is paired with a smooth flagellum. In both groups, the high surface-to-volume ratio of filamentous hyphae enhances nutrient uptake: although oomycetes descended from photosynthetic ancestors, they no longer have plastids. Laminaria ( kombu in japan) in soup and porphyra (japanese. In laminaria, the sporophyte and gametophyte are structurally different, or heteromorphic. In other algae, the alternating generations look alike (isomorphic) but differ in the chromosome number. Formation of colonies of individual cells (e. g. , volvox).
