(b)Binary fission-The term “fission” indicates “to divide”. Through binary fission, the parent cell divides into two cells. ... Example: Amoeba and euglena exhibit binary fission. It is one of the simplest and uncomplicated methods of asexual reproduction
Multiple fission-Multiple fission is the process of asexual reproduction in which instead of 2 daughter cells, many daughter cells are produced from the parent cell. In this, the nucleus undergoes repeated division to produce a large number of nuclei. Each nucleus along with little bit of cytoplasm forms a membrane around it.
