The availability of oxygen, the most capable electron acceptor on our planet, allowed the development of highly efficient energy production from oxidative phosphorylation, which shaped the evolutionary development of aerobic life forms from the first multicellular organisms to the vertebrates.
Cyanobacteria possess the niche as Primary producers- foundation of the food chains and ecosystems to support higher trophic-level organisms
Origin of plants & Chloroplasts
Endosymbiosis theory- the idea that when an eukaryote engulfed another prokaryote, instead of digesting it into food, it forms a kind of symbiosis relationship
Possible donator of photosynthetic ability to some eukaryotes who later evolved into plants.
