Question

Quizplus · Accepted Answer

The fact that chloroplasts use exclusively chlorophyll a and b is not evidence for the endosymbiotic theory, as this characteristic can also be found in other types of photosynthetic organisms. The other three choices are supportive of the endosymbiotic theory: (A) chloroplasts have a single circular chromosome like bacterial cells, (B) chloroplasts use two linked photosystems like Cyanobacteria, and (D) Chloroplasts in some algae are surrounded by two membranes, which is consistent with engulfment by a host cell.
