Marine life asexually by binary fission, fragmentation, or budding; unlike bacteria and eukaryotes, no known species forms spores. Archaea are particularly numerous in the oceans, and the archaea in plankton may be one of the most abundant groups of organisms on the planet. Archaea are a major part of Earth's life and may play roles in both the carbon cycle and the nitrogen cycle. Of eukaryotic groups, the protists are most commonly unicellular and microscopic. This is a highly diverse group of organisms that are not easy to classify. Several algae species are multicellular protists, and there are marine slime molds have
Dunaliella strain is reported to have oil yield of about 37% (organic basis). "D. tertiolecta" is a fast-growing strain and that means it has a high CO sequestration rate as well. Dunaliella Dunaliella is a genus of the algae family Dunaliellaceae. "Dunaliella" sp. are motile, unicellular, rod to ovoid shaped (9−11 µm) green algae (Chlorophyceae), which are common in marine waters. The organisms are relatively simple to cultivate and do not clump or form chains. The best-known species is the extremely salt tolerant "Dunaliella salina" Teodor. A new species of "Dunaliella" was discovered in the Atacama Desert in 2010. It is
