what are the similarities between chlamydomonas and yeast
Answers
Chlamydomonas reinhardtii features are ovate in shape, about 10 um, unicellular with a distinct cell wall, and a single chloroplast in close proximity to the nucleus. The nucleus is typically located in the center and with a distinct nucleolus. There is an eyespot and one or several contractile vacuoles
Explanation:
Chlamydomonas is a genus of green algae consisting of about 325 species[2] all unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae".[3] Chlamydomonas is used as a model organism for molecular biology, especially studies of flagellar motility and chloroplast dynamics, biogenesis, and genetics. One of the many striking features of Chlamydomonas is that it contains ion channels (channelrhodopsins) that are directly activated by light. Some regulatory systems of Chlamydomonas are more complex than their homologs in Gymnosperms, with evolutionarily related regulatory proteins being larger and containing additional domains.[4]
The green yeast has been a denizen of the laboratory for decades. It is easy to grow in liquid cultures and has fascinating morphology and behaviors. Relatively recently, Chlamydomonas research has touched on applied topics that would use metabolism for the purposes of industrial production, as well as basic research. A major topic concerns the eyespot, which is recognized microscopically by carotenoid-rich lipid droplets (Nagel et al. 2003). These spots catch light and reflect it back toward membrane-bound photoreceptors, channel rhodopsin, in an apparent efficiency exercise. Biophysicists have been using the Chlamydomonas eyespot to study photoreception, leading to the expression of channel rhodopsin in a number of cell types that are not typically photoreceptive.
