Document Summary
January 29, 2013: grey chloroplasts are cyanelles. They have two whiplash flagella like the green lineage. Like red and cyanobacteria, they have phycobilisomes as secondary light harvesting mechanisms: red, greens and greys are the true plants and they have primary endosymbiosis. They are treated as archaeplastida: brown is still existing because the host eukaryotic cells represent a separate thing. There are some browns that are sister to the true plant (archaeplastida), and there are some that are sister to those two together (separate lineage/branch) Secondary plants are euglenophyle (euglenas) and are a separate branch: bikonts (two flagella) and unikonts are completely separate branches of eukaryotes. Unikonts are where all the animals and fungi are: browns are still fragmented but they still retain similar characteristics. History of taxonomy: apothecaries (2nd-15th century/middle ages) - accounts of plants were entirely about medicinal plants. Illustrations that accompanied the book was getting lousier.
