Question

what is the normal name of chlamydomonas

Answer 1

Chlamydomonas is a genus of green algaeconsisting of about 325 species[1] all unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae".[2]Chlamydomonas is used as a model organismfor molecular biology, especially studies of flagellar motility and chloroplast dynamics, biogeneses, and genetics. One of the many striking features of Chlamydomonas is that it contains ion channels (channelrhodopsins) that are directly activated by light. Someregulatory systems of Chlamydomonas are more complex than their homologs in Gymnosperms, with evolutionarily related regulatory proteins being larger and containing additional domains.[3]

Molecular phylogeny studies indicated that the traditional genus Chlamydomonas defined using morphological data was polyphyleticwithin Volvocales, and many species were reclassified (e.g., in Oogamochlamys, Lobochlamys), and many other "Chlamydomonas" lineages are to be reclassificated.[4][5][6]
