Chlamydomonas

 
Britannica Concise Encyclopedia: Chlamydomonas
Home > Library > Miscellaneous > Britannica Concise Encyclopedia

Genus of single-celled green algae considered to be primitive life-forms of evolutionary significance. The cell has a spherical cellulose membrane, an eyespot, and a cup-shaped, pigment-containing chloroplast. Though capable of photosynthesis, Chlamydomonas may also absorb nutrients through the cell surface. It is found in soil, ponds, and ditches polluted by manure. It may colour water green. A red-pigmented species turns melting snow red.

Chlamydomonas is a genus of green alga. They are unicellular flagellates. 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 that are directly activated by light, such as channelrhodopsin.
