Question

In the lab, you prepared chromatograms for a variety ofphotosynthetic organisms. All of these organisms were found tocontain chlorophyll a. Fossil and molecular evidence tells us thatthe cyanobacteria evolved before algae and plants. Based on yourunderstanding of the origin of the eukaryotic chloroplast, what isthe significance of the ubiquity of chlorophyll a?
My answer: Eukaryotic chloroplast evolved based on the theoryof serial endosymbiosis; a larger prokaryotic cell engulfed asmaller......blah blah you know what it is. According to this, thesignificance of the ubiquity of chlorophyll a suggests a sharedancestry among all the organisms.
