Photosynthesis spread through most of the eukaryotic superkingdoms by repeated episodes of endosymbiosis of photosynthetic eukaryotic organisms.

Question

Quizplus · Accepted Answer

This is true. Photosynthesis evolved in prokaryotic organisms and was then transferred to eukaryotes through endosymbiosis, where a photosynthetic prokaryote was engulfed by a eukaryotic host and eventually became a permanent organelle known as the chloroplast. This process occurred multiple times in different lineages, leading to photosynthesis in multiple eukaryotic superkingdoms.
