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 species are widely distributed worldwide in soil and fresh water, of which Chlamydomonas reinhardtii is one of the most common and widespread. [1] C. reinhardtii is an especially well studied biological model organism , partly due to its ease of culturing and the ability to manipulate its genetics.
Chlamydomonas moewusii is a species of unicellular green alga belonging to the genus Chlamydomonas. C. moewusii is typically a freshwater species and occupies a significant position as a model organism for various scientific studies due to its relatively simple cellular structure and ease of cultivation.
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.
Protococcus C.Agardh, 1824 accepted as Chlamydomonas (synonym) Sphaerellopsis Korshikov, 1925 accepted as Vitreochlamys (synonym) [4] The family is known to be non-monophyletic, with clades not aligning to traditionally defined morphological groupings. [5]
In contrast to thermotaxis, phototaxis has been extensively studied in Chlamydomonas. Two flagella of Chlamydomonas beat in a breast-stroke like pattern during forward swimming and, during phototaxis, Chlamydomonas cells make by a turn toward or away from a light source by controlling the balance of the propulsive forces generated by the two ...
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.
This symbiotic relationship is exploited by humans in agriculture. In Asia, Azolla plants containing Anabaena species are used as biofertilizer where nitrogen is limiting [8] as well as in animal feed. [9] Different strains of Azolla-Anabaena are suited for different environments and may lead to differences in crop production. [10]
