The objective of amitosis in bacteria is to increase progeny and propagation of generation.
Amitosis: The nuclear material containing a circular chromosome, elongates. A constriction develops in the middle portion of a chromosome. When constriction increases the circular chromosome, it divides into two halves. In the beginning, the chromosome is attached to the cell wall. But as the cell increases in size, the two halves of chromosome separate. After that, the constriction develops into the cell wall. When constriction increases, the bacterial cell divides into two daughter cells.
