Binary fission and budding are the modes of asexual reproduction. In binary fission, two organisms are produced from a single unicellular parent organism. First, the nucleus divides followed by the division of the cytoplasm. Ultimately two daughter organisms are formed. In budding, the body wall of the unicellular organism is produced outwardly in the form of a bulge as a result of repeated mitotic division in the cells. The bulge is called bud. The bud gradually enlarges in size and develops into a new organism.
