Chlamydomonas (/ ˌ k l æ m ɪ ˈ d ɒ m ə n ə s,-d ə ˈ m oʊ-/ KLAM-ih-DOM-ə-nəs, -də-MOH-) is a genus of green algae consisting of about 150 species [2] of unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae". [3]
Chlamydomonas reinhardtii is a single-cell green alga about 10 micrometres in diameter that swims with two flagella. It has a cell wall made of hydroxyproline -rich glycoproteins , a large cup-shaped chloroplast , a large pyrenoid , and an eyespot apparatus that senses light.
Chlamydomonadaceae is a family of algae within the order Chlamydomonadales. [1] Traditionally, it has been defined as containing single-celled flagellates with a cell wall. [2] Cells of the Chlamydomonadaceae are motile and have one, two, or four flagella.
The handedness of the spiral is robust and is guaranteed by the chirality of the cilia. The two cilia of green algae have different beat patterns and functions. In Chlamydomonas, the phototransduction cascade alters the stroke pattern and beating speed of the two cilia differentially in a complex pattern.
The name Chlamydomonas nivalis is of compound Greek and Latin origin. Chlamydomonas is ultimately derived from the Ancient Greek χλαμύς (khlamús, "cloak, mantle") and μονάς (monás, "solitary"), [8] while nivalis, from the Latin nivālis, translates to 'found growing in or near snow', as this species of algae are only found associated with snow or near snowy areas.

The eyespot apparatus (or stigma) is a photoreceptive organelle found in the flagellate or (motile) cells of green algae and other unicellular photosynthetic organisms such as euglenids.
Chlamydomonas elegans is a species of freshwater green algae. It is commonly found in rainwater pools and other small, temporary bodies of water. [2] Chlamydomonas elegans is a unicellular organism with ellipsoidal-ovoid cells, which are usually flattened on one side, and rounded at the ends. Cell bodies are 23–30 μm long and 13–15 μm wide.
Chlamydomonas is not a Protist but a Plant--Kupirijo 12:30, 19 October 2006 (UTC) I have checked the history and it is very annoying when people change it to Protists without discussion. --Kupirijo 12:30, 19 October 2006 (UTC) Actually, Chlamydomonas is currently considered to be a protist.
