Cyanobacteria are the primary biological agents capable of photosynthesis, as described in [1], and their evolutionary history is defined by their role in endosymbiotic events that spread photosynthetic capabilities to other organisms [2]. Furthermore, the potential for photosynthesis in cyanobacteria is a key metric for evaluating the habitability of stellar systems [3].

claimCyanobacteria capable of photosynthesis evolved before eukaryotic cells and were engulfed by larger bacterial cells to become chloroplasts.
claimRed algae, brown algae, golden algae, and stramenopiles became photosynthetic through secondary or tertiary endosymbiotic events, where they endosymbiosed cells that had already endosymbiosed a cyanobacterium.
