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]
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]
Gonium colony of 16 cells at nominal magnification of 450x. Gonium is a genus of colonial algae, a member of the order Chlamydomonadales.Typical colonies have 4 to 16 cells, all the same size, arranged in a flat plate, with no anterior-posterior differentiation.
Schematic representation of a Euglena cell with red eyespot (9) Schematic representation of a Chlamydomonas cell with chloroplast eyespot (4). 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 moewusii is a heterothallic species, exhibiting distinct behavioral differences between the gametes of its two mating types. When suspensions containing 'plus' and 'minus' gametes are mixed under light, they form clumps that eventually separate into pairs after a few minutes. These pairs then swim freely for 4–8 hours.
By Keith Morrison Taking the phrase of "putting it under the microscope" quite literally, the Nikon Small World contest recently announced its winners for 2014. Now in its 40th year, the contest ...
Volvox colony: 1) Chlamydomonas-like cell, 2) Daughter colony, 3) Cytoplasmic bridges, 4) Intercellular gel, 5) Reproductive cell, 6) Somatic cell. Volvox is a polyphyletic genus in the volvocine green algae clade. [2]
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.
