Is there any evidence that the plants, algae, and some bacteria that do photosynthesis?
Plants, algae and some bacteria that do photosynthesis are NOT exactly more closely related to each other thatn they are to animals, fungi and bacteria that don’t photosynthesize. Plants, animals, algae and fungi are more closely related to each other, even if not all of them can photosynthesize, simply because they are eukaryotes. Photosynthetic bacteria are also MORE related to nonphotosynthetic bacteria compared to plants, because they are both prokaryotes. Eukaryotes and prokaryotes both originated from a universal ancestor, and from there they diverged into their own phylogenetic distinctions. BUT, it just so happened that they have the the same structures that they use to photosynthesize. This is mainly because of PHOTOSYNTHETIC BACTERIA that incorporated into eukaryotic cells to give their photosynthetic qualities–meaning that, eukaryotes and prokaryotes definitely are NOT more related to their photosynthetic counterparts. But that they are just linked by common structures.
