The conclusion drawn from the fact that DNA analysis of all chloroplasts reveals that they are monophyletic is Endosymbiosis of the same species of cyanobacteria occurred multiple times in cells that evolved into red, green, and brown algae.
Most scientists agree that non-photosynthetic eukaryotic hosts originally acquired photosynthetic prokaryotic endosymbionts, which led to the formation of plastids. It is also acknowledged that non-photosynthetic eukaryote hosts frequently took on photosynthetic eukaryotes as endosymbionts in order to create secondary plastids.
It is shown that primordial plastids had a single, or "monophyletic," genesis. The red, green, and glaucophyte plastids are thought to belong to a single group, either as a subgroup of oxygenic photosynthetic prokaryotes or as a sister group, according to the monophyletic hypothesis of plastid genesis.
Therefore,Endosymbiosis of the same species of cyanobacteria occurred multiple times in cells that evolved into red, green, and brown algae.
