In this type, the cell division along a diagonal. Oblique: It occurs in dinoflagellates like Ceratium.Here, the cell division occurs at a horizontal axis. Transverse: It commonly occurs in ciliates like Paramecium.Here, the cell division occurs along a vertical axis that divides a cell’s nucleus and cytoplasm longitudinally. Longitudinal: It occurs in flagellates (like Euglena) and ciliates (like Vorticella).But, it always happens at right angles to the expanding nucleus. The plane of cell division is variable, or it occurs along any axis. Irregular: It occurs in amoebae having irregular symmetry.Using binary fission, the cell can divide irregularly, transversely, longitudinally and obliquely.It does not give any genetic variability to offspring, as they are identical.Binary fission occurs to increase the population of organisms.Besides prokaryotes, some simple eukaryotes and eukaryotic cell organelles may also undergo binary fission.Offspring produced by binary fission are genetic clones of their parents.Once a septum forms completely, the cell splits into two identical daughter cells.Later, the exchange of cytoplasmic material occurs between the separating cells.
