Split off from Binucleusphotoedo, this little cell has gained a fatter, rounder shape to catch more sunlight. It has also developed a pair of light-sensitive organelles and a pair of flagella, which work together to help it locate more light and swim towards it. Thanks to its mobility, it has spread considerably to many coastal regions which previously had no photosynthesizers present. It is otherwise very similar to its ancestor, being a single photosynthesizing cell with 2 nuclei. During the process of photosynthesis, it converts carbon dioxide into oxygen.
