Fission in the mitotic phase of cell division of green algae forms autospores. Cells may use different methods to produce different numbers of autospores or multinucleated autospores; for example, the Dictyochloropsis genus of algae can produce between 4 and 16 autospores when they reproduce.
Binary fission is generally rapid, though its speed varies between species. For E. coli, cells typically divide about every 20 minutes at 37 °C. [11] Because the new cells will, in turn, undergo binary fission on their own, the time binary fission requires is also the time the bacterial culture requires to double in the number of cells it ...
Dinophysis mainly divide by binary fission. [4] Dinophysis chloroplasts are usually rod-shaped or granular and yellow or brown colored. [4] Some Dinophysis spp. take up kleptoplastids when feeding. Toxic Dinophysis produce okadaic acid, dinophysistoxins, and pectenotoxins, which inhibit protein phosphatase and cause diarrhea. [6]

Paramecium reproduction is asexual, by binary fission, which has been characterized as "the sole mode of reproduction in ciliates" (conjugation being a sexual phenomenon, not directly resulting in increase of numbers). [3] [32] During fission, the macronucleus splits by a type of amitosis, and the micronuclei undergo mitosis. The cell then ...

Dogs may be exposed by drinking the water, eating the algae or licking it off their fur," according to the city. "People can have symptoms from these toxins as well. Because humans are less likely ...
Volvox globator is a species of green algae of the genus Volvox. It was originally described by Carl Linnaeus in his 1758 work Systema Naturae. [1] In 1856 its sexuality was described by Ferdinand Cohn and is the same as Sphaeroplea annulina. [2] It is colonial flagellate found in freshwaters.
