Document Summary

The protists: diversity and life cycles: a very large and diverse group, they exhibit all the diversity of sexual life cycles, eukaryotes (the least know about, eg. Amoeba: can be unicellular and pathogenic, can cause sleeping sickness when blood infected by some protist, eg. Green algae (some protists are among the largest things on earth. Red alga to other stuff (3 or more membranes) new clade (sar clade)-were first not photosynthetic but became photosynthetic after taking red alga: lateral gene transfer event in previous point. Characteristics: eukaryotes that are not fungi, plant or animal, most (but no all) are small, aerobic and aquatic and motile, many are parasitic with humans eg. Ingestive chemoheterotroph carried out by protists call protozoa: photoautotrophs eg algae (not a clade). Called phytoplankton float around in water (diatoms, dinoflagellates, cyanobacteria: dinoflagellates when agitated give off light energy. Bioluminescence: little animals come in to eat dinoflagellates and they light up which brings the predators of the predators.
