From the web site above: “Ostreococcus belongs to the Prasinophyceae, an early-diverging class within the green plant lineage, and is reported as a globally abundant, single-celled alga thriving in the upper (illuminated) water column of the oceans. The most striking feature of O. tauri and related species is their minimal cellular organization: a naked, nearly 1-micron cell, lacking flagella, with a single chloroplast and mitochondrion.”
