Question

Quizplus · Accepted Answer

Cyanobacteria are a group of photosynthetic bacteria that use chlorophyll a and release oxygen during photosynthesis. They are not the only group of photosynthetic bacteria but are one of the most well-known. They are also known as blue-green algae, although they are not algae. Cyanobacteria do not reproduce sexually but can reproduce asexually. They are typically obligate aerobes, meaning they require oxygen to survive.
