What prokaryotic cells that were the first to add significant quantities of oxygen to Earth's atmosphere are classified as?

Prokaryotic cells that were the first to add significant quantities of oxygen to Earth's atmosphere are classified as cyanobacteria. Cyanobacteria are photosynthetic bacteria that played a crucial role in the Great Oxidation Event, releasing oxygen as a byproduct of photosynthesis. Their activity contributed to the oxygenation of Earth's atmosphere and paved the way for the evolution of aerobic life forms.
