Micromonas pusilla
Description and significance
M. pusilla is an aquatic microorganism which is distributed worldwide. It is currently the only classified species within the genus Micromonas. The species contains at least three distinct clades: subtropical/tropical, temperate, and polar. M. pusilla is generally less than 2 µm in length and is therefore classified as a picophytoplanktonic species. It is pear-shaped with a single flagellum which has microtubules at the end. M. pusilla is one of the most abundant microorganisms within marine ecosystems and it is the smallest known single-celled eukaryotic organism.
Genome structure
Research is currently being done on the genome of Micromonas pusilla, so there is not an abundance of knowledge on it. The genome is 15 Mb.
Cell structure and metabolism
Micromonas pusilla is a green algal species and gains energy through photosynthesis. It uses carbon fixation to produce organic molecules, which is driven by photosynthesis. The microorganism contains only one mitochondrion which produces adenosine triphosphate, or ATP, used for cellular energy. M. pusilla also contains a Golgi body which is an organelle used in the process of protein and lipid production and synthesis.
Ecology
Micromonas pusilla is an aquatic picophytoplankton and inhabits waters around the world.
