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]
The starting point of Scenedesmus and related algae is in 1820, when Pierre Jean François Turpin observed these algae under a microscope. He classified them under the diatom genus Achnanthes; later authors moved them to different groups, until it was finally classified as a green alga. [1]
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.
However, recent work has shown that RuBisCO in the pyrenoid matrix of the green alga Chlamydomonas is not in a crystalline lattice and instead the matrix behaves as a phase-separated, liquid-like organelle. [23] In Porphyridium and in Chlamydomonas, there is a single highly conspicuous pyrenoid in a single chloroplast, visible using light ...
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.
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.
A condenser between the stage and mirror of a vintage microscope. Condensers are located above the light source and under the sample in an upright microscope, and above the stage and below the light source in an inverted microscope. They act to gather light from the microscope's light source and concentrate it into a cone of light that ...
