Binary Fission
Binary Fission
Binary fission is an asexual method of reproduction in organisms. In binary fission the parent organism splits (or divides) to form two new organisms. When this happens, the parent organism ceases to exist and two new organisms come into existence. The unicellular organism (or unicellular animal) called Amoeba reproduces by the method of binary fission.
Binary fission can be simple i.e. the cytoplamic division takes place through any plane, as seen in amoeba and Bacteria or it may be transverse, when plane of cytoplasmic division coincides wuith the trnsverse aixs of the organism, as seen in Paramecium, or it may be longitudinal when the cytoplasmic division coincides with the longitudinal axis of the individual, as seen in Euglena.
Multiple fission : In case of multiple fission repeated divisions of parent nucleus are followed by cytoplasmic division leading to many daughter cells occurs in malarial parasite Plasmodium.
