Chlamydomonas is multicellular
WebThis chapter details what is known about these multicellular relatives of Chlamydomonas, including their phylogeny, ecology, morphologies, life histories, genetics, genomes, and evolution. It highlights the most compelling questions that remain unanswered about their biology and origins, and it describes the available tools that should make it ... WebChlamydomonas is considered a volvocine algae, a class of algae comprised of several species of increasingly complex multicellularity. The main representatives of this family are C. reinhardtii, Gonium pectorale, Pandorina morum, Eudorina unicocca, Pleodorina californica, and V. carteri ( Hallmann, 2011 ).

WebChlamydomonas is a genus of 325 species of unicellular green algae. The flagellates can be found living in droplets of water in freshwater, seawater, stagnant water, and even within moist soil. Chlamydomonas are studied as model creatures thanks to their unique flagellar movements and physiology. WebChlamydomonas reinhardtii is a unicellular volvocine alga having two mating types: mating type plus (mt+) and mating type minus (mt-), which are controlled by a single, complex mating-type locus. Sexual adhesion between the gametes is mediated by sex-specific agglutinin molecules on their flagellar membranes.
