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.
Asexual: binary fission from a partitioned parent cell. Sexual: Conjugation to form a hypnozygote. The Closterium peracerosum-strigosum-littorale (C. psl) complex is a unicellular, isogamous charophycean alga cells that is the closest unicellular relative to land plants. These algae are capable of forming two types of dormant diploid zygospores.
Reproduction among these organisms is asexual by binary fission, during which the diatom divides into two parts, producing two "new" diatoms with identical genes. Each new organism receives one of the two frustules – one larger, the other smaller – possessed by the parent, which is now called the epitheca ; and is used to construct a second ...
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 ...
Paramecia reproduce asexually, by binary fission. During reproduction, the macronucleus splits by a type of amitosis, and the micronuclei undergo mitosis. The cell then divides transversally, and each new cell obtains a copy of the micronucleus and the macronucleus. [10] Fission may occur as part of the normal vegetative cell cycle.
Waters off the state’s southeastern coast are running about three and a half degrees higher than normal in Fahrenheit, with waters in the Florida Keys up a stunning seven degrees above average.

This genetically distinct individual can then proliferate through binary fission. Some argue that this is not true reproduction but actually a form of growth. [ 4 ] Fission is often prompted in the autumn by a decrease in the abundance of food and follows sexual spawning in summer.
