The cyanobacterium Prochlorococcus is the smallest and most abundant photosynthesizing cell in the ocean. The hidden complexity of this microorganism has fascinated scientists for years. Ecotypes of Prochlorococcus live on the surface of the ocean down to 200m and in total, this organism is responsible for about 5% of global photosynthesis. Interestingly, it has about four times as many genes as humans, over 80,000!
Science Magazine produced the video below to highlight the amazing characteristics of this microorganism. For more, read about Prochlorococcus and the scientists who study them here:
