Binary fission is a form of asexual reproduction in which one cell divides into two equal in size daughter cells. It commonly occurs in bacteria and protists. The DNA is replicated and then cell growth occurs. Eventually, the cell membrane grows inward and splits into two daughter cells.There are three different types of binary fission. These are irregular, transverse and longitudinal. In irregular binary fission which occurs in the ameba, when the cytoplasm divides by cytokinesis, it make take place along any plane, however, it will be at a right angle to the elongated dividing nucleus.
It means the amoeba can divide into two organism in any plane. It can divide horizontally, vertically, or diagonally. In any other plane. But in organism, that have whip like structure, they cannot divide in any plane. They divide in only one plane i.e. they divide according to whip like structure.
