Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. Spirogyra species, of which there are more than 500, are commonly found in freshwater ...
The Zygnemataceae are cosmopolitan, but though all generally occur in the same types of habitats, Mougeotia, Spirogyra, and Zygnema are by far the most common; in one study across North America, [3] 95% of the Zygnemataceae collected were in these three genera. Classification and identification is primarily by the morphology of the conjugation ...
Spirogyra at Kent University, 1971. Their debut album, St Radigunds, was recorded at Sound Techniques studio, produced by Robert Kirby and engineered by Jerry Boys. Named after the Canterbury street on which the members lived, its lyrics express the anti-capitalistic, anti-materialistic orientation of the band and of the broader Canterbury scene.
The body plan of Zygnematophyceae is simple, and the group appears to have gone through a secondary loss of morphological complexity. [8] The most basal members are unicellular, but filamentous species have evolved at least five times, [9] and a few species form colonies. [7]
The Zygnematales (Greek: ζυγός (zygós) and νῆμα (nḗma) (), νήματος (nḗmatos) ()), also called the Conjugatales, [1] are an order of green algae, [2] comprising several thousand different species in two families.
Spirogyra measures approximately 32–115 μm in width. Each cell contains 2–10 chloroplasts in a ribbon, in contrast to the closely related genus Spirogyra , which has chloroplasts in a coil. [ 1 ] [ 2 ] Molecular phylogenetic studies have placed Sirogonium inside a clade consisting of Spirogyra species; in other words, Spirogyra is ...
