Quizplus · Accepted Answer

Primary endosymbiosis is the process by which a eukaryotic cell engulfs a prokaryotic cell, which then evolves into an organelle. Chloroplasts, the organelles responsible for photosynthesis, are believed to have arisen from primary endosymbiosis of a photosynthetic cyanobacterium by a eukaryotic cell. Therefore, chloroplasts are the structure that arose from primary endosymbiosis in the clade of photosynthetic eukaryotes.
