Question: What is found in Prochlorococcus and essential for photosynthesis?

Related documents: [0]  [DOC] Chlorophyll (also chlorophyl) is any of several closely related green pigments found in cyanobacteria and the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, "chloros" ("green") and φύλλον, "phyllon" ("leaf"). Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light. [END] 
[1]  [DOC] Prochlorococcus is a genus of very small (0.6 µm) marine cyanobacteria with an unusual pigmentation (chlorophyll "a2" and "b2"). These bacteria belong to the photosynthetic picoplankton and are probably the most abundant photosynthetic organism on Earth. "Prochlorococcus" microbes are among the major primary producers in the ocean, responsible for a large percentage of the photosynthetic production of oxygen. Analysis of the genome sequences of 12 "Prochlorococcus" strains show that 1,100 genes are common to all strains, and the average genome size is about 2,000 genes. In contrast, eukaryotic algae have over 10,000 genes. [END]
