Cyanobacteria (Blue-green bacteria, blue-green algae)

download

In the video above you can observe a cyanobacteria and a diatom, both enclosed in a round structure, most probably an amoeba from the genus Arcella. The blue-green algae (the cyanobacteria) are Prokaryotic organisms – unlike Eukaryotic organisms, their morphology is simple and primitive, their cells lacking a nucleus. However, the cyanobacteria are photosynthetic organisms – they use, the same way plants (eukaryotic organisms) do, the light and the carbon dioxide in order to obtain energy, releasing oxygen in the same time.
