Document Summary
Genetics and evolution - lecture 18 - week 9. Protista: simple eukaryotic cell (almost all are aquatic or live in moist surrounds, producers: several divisions of photosynthetic organisms, consumers: ciliates, colourless agellates, parasites and pathogens, absorbers and recyclers: slime and water moulds. Paulinella, glaucophyta and rhodophyte have the same pigments are cyanobacteria (a, phycocyanin and phyocoerythin) Evolution: chloroplasts derived from red (crytomonads) algae and green (chlorachniophytes) algae, eugleninds: protistan pirates with chloroplasts from a green algae (chlorophyll a and b) Green algae (chlorophyta: primary endosymbionts, enormous variation, diverse morphology, progenitors of land plants, major biofoulers and pollutes, solar energy and biofuels. Brown algae (phaeophyta: alginates: emulsi ers and stabilisers (cheap substitute for carrageenans) Diatoms (bacillariophyta: major producer in all aquatic habitats, protistan pirates: chloroplasts from a red alga and contain chlorophyll a+c and the brown pigment fucoxanthin (same brown algae)
