-methyl-hopanoids are biomarkers for this phylum. Seven genera in this phylum produce anatoxin-a. The phylum's order Nostocales contains motile, filamentous structures called hormogonia. Anabaena and other members of this phylum have heterocysts, but all members of this taxon have carboxysomes to limit photorespiration. Most stromatolites are formed through the accumulation of (*) mats of organisms in this phylum. They made the Earth's atmosphere oxidizing during the Great Oxygenation Event. Lynn Margulis advanced the theory that plastids originated from these organisms due to endosymbiosis. For 10 points, name this phylum of photosynthetic bacteria also called blue-green algae.
