‘Binary’ means 2 . As the name suggests, binary fission involves the division of a cell into two daughter cells . Bacteria, Paramoecium , and Leishmania (organism causing kala-azar) show binary fission.
In this type of fission, the parent cell divides to produce more than two daughter cells at the same time . Example malaria causing parasite Plasmodium .
