Answer

Brief Explanations:

Chloroplasts are thought to have originated from a single - line of cyanobacteria through endosymbiosis. However, the group of photosynthetic eukaryotes is not monophyletic as different lineages have acquired chloroplasts in different ways or have lost them over time.

Answer:

All chloroplasts likely evolved from a single line of cyanobacteria, however, photosynthetic eukaryotes are not monophyletic.
