- Evidence indicating the chloroplasts were originally free-living prokaryotes that subsequently evolved a symbiotic relationship with a eukaryotic host includes all of the following except: Ability of chloroplasts to synthesize all their own proteins Presence of circular DNA in chloroplasts and in free-living prokaryotes Similarities of rRNA sequences between chloroplasts and free-living prokaryotes Similarities of structures between chloroplasts and some contemporary free-living prokaryotes CWhy do cyanobacteria possess heterocysts? View Available Hint(s) for Part A Heterocysts shield the organism's nitrogen fixation enzymes from oxygen. Heterocysts serve as a primitive nucleus in these bacteria. Heterocysts are reproductive structures similar to endospores in other bacteria. Bacterial photosynthetic pigments are located in heterocysts.The non-protein component of the transmembrane complex used by the salt-loving archaeobacterium Halobacterium halobium, which uses sunlight to create a proton gradient for ATP synthesis, is called: bacteriochlorophyll chlorophyll bacteriorhodopsin retinal cytochrome c
