That's interesting. What makes cyanobacteria distinct from plants?

[–] SwingingTheLamp@midwest.social 4 points 1 month ago

The first thing that comes to mind is that bacteria are prokaryotes, while plants are eukaryotes. They have internal membranes, called thylakoids, in which they do photosynthesis, but chloroplasts in plants are fully-developed organelles with their own DNA. If I recall correctly, the current thinking is that chloroplasts developed from endosymbiotic cyanobacteria.
