Prokaryotic cells divide by binary fission and eukaryotic cells divide by mitosis.
Binary fission and mitosis result in daughter cells genetically identical to the parent cell.
In fission, the duplicated circular chromosomes (there are now two identical chromosomes) each attach to the bacterial cell membrane.

 Binary fission - Wikipedia, the free encyclopedia
Binary fission is the form of asexual reproduction used by most prokaryotes and protists to reproduce.
Binary fission is asexual; offspring are supposed to be genetically identical to the parent cell, but due to mutation, daughter cells may have slightly differed genetic makeups.
Organisms that reproduce through binary fission generally grow exponentially.

 Ternary and quaternary fission
A peculiarity of low energy fission is the asymmetry of the mass division: in the lighter actinides from Thorium to Einsteinium, the nuclei disintegrate asymmetrically in the sense that predominantly a heavier and a lighter fragment is produced.
Stated in other words, binary fission should correspond to a single rupture of the neck filament, while in ternary fission the neck is cut at two places before the stubs of the neck can recede and be absorbed by the fragments.
It should be noted that the lightest fragment in the light group is complementary to the heaviest fragment in the heavy group (asymmetric fission) and vice versa for the lightest fragment in the heavy group and the heaviest fragment in the light group (near symmetric fission).

 The Sections
Members of Section I are unicellular cyanobacteria whose cells may be spherical, cylindrical or oval; most reproduce by binary fission, which may occur in one, two or three planes; some reproduce by asymmetric binary fission (budding); colonial forms are held together by mucilage or sheath.
Members of Section III are filamentous cyanobacteria whose trichomes reproduce by binary fission in a single plane at right angles to the long axis and are consequently uniseriate.
Cyanobacteria assigned to Section IV are filamentous organisms that reproduce by binary fission in a single plane to produce uniseriate trichomes.

However, it is not uncommon to observe closely-joined binary pairs of shells (usually one shell slightly smaller than the other) connected by strands of cytoplasm in living colonies (as in Figure 5).
Until we have more substantial evidence about the number of species that undergo binary fission, and the frequency of occurrence in a population, it will be difficult to make inferences about its significance for radiolarian ecology and population dynamics.
However, if there are further stages of binary fission within each generation in some radiolaria (as suggested previously in the literature and reported further here), this would permit additional stages of asexual proliferation of the radiolaria without swarmer production.

Because most bacteria grow by binary fission, doubling in cell number usually occurs at the same rate that individual cells grow and divide.
Binary fission is the process by which most procaryotes replicate.
Binary fission generally involves the separation of a single cell into two more or less identical daughter cells, each containing, among other things, at least one copy of the parental DNA.

 The Discovery of Fission, 1938-1939
Fission, the basis of the atomic bomb, was discovered in Nazi Germany less than a year before the beginning of the Second World War.
It soon became clear that the process of fission discovered by Hahn and Strassmann had another important characteristic besides the immediate release of enormous amounts of energy.
The energy released when fission occurred in uranium caused several neutrons to "boil off" the two main fragments as they flew apart.

 Binary Fission
Binary fission is used by most prokaryotes for asexual reproduction.
The fission process begins when the DNA of the mother cell is replicated and joins into a circular structure, pair by pair; each circular DNA strand then attaches to the plasma membrane.

 Binary Fission   (Site not responding. Last check: 2007-10-03)
The cell replication of prokaryotic cells is known as binary fission.
These archaic cells reproduce simply by replicating their single chromosome into a duplicate ring and then dividing the cell into two distinct "daughter cells".
Since prokaryotes lack a cell nucleus and various other organelles common to eukaryotic cells, they have the single replicated chromosome move to one end of the cell and "asexually" replicate, hence the term "fission".

These images, captured from video using a Snappy video grabber, illustrate the final stages of protozoan asexual reproduction (a process known as "binary fission").
Binary fission generally produces daughter cells with genetic material (DNA) identical to that of the parent.
It is an efficient way for protozoa to increase in number during periods when environmental conditions are relatively stable.

Stars are born from clouds of gas and dust as singular stars, pairs of stars--called binary systems--or clusters.
Binary star systems exhibit a wide range of orbital periods--from days to tens of thousands of years--and mean distances from one another, with a median at about 50 astronomical units (AU).
The next step is to perform hydrodynamics simulations of evolved unequal mass binary systems, in which there is mass transfer between the stars, which is the topic of Motl's dissertation work.

Discuss the advantages and disadvantages of asexual reproduction by making reference to different types of asexual reproduction in plants and animals(Refer to cloning, binary fission, formation, vegetative reproduction, parthenogenesis, budding and fragmentation).
To ensure the continuation of the species, plants and animals use two methods of reproduction - sexual and asexual.
Asexual reproduction is more reliable than sexual, because there are less steps to follow and therefore less can go wrong, for instance pollen transfer is very flimsy and since asexual reproduction doesn't need this, it is more reliable.
