Different Types of Binary Fission

Irregular Binary Fission

  • Cytokinesis (the division of the cytoplasm) occurs along a plane perpendicular to that of Karyokinesis.

  • The plane of cytokinesis is always perpendicular to plane on which Karyokinesis occurred.

  • Karyokinesis is the division of a cell nucleus during mitosis.

Longitudinal Binary Fission

  • It is a type of mitosis.

  • Here fission/cytokinesis occurs along a longitudinal axis.

Oblique Binary Fission

It is a type of fission that has no occurrence.

Transverse Binary Fission

In this case cytokinesis occurs along the transverse axis.

Differences between Binary Fission and Multiple Fission

Difference between Binary Fission and Multiple Fission

Binary fission

Multiple fission

Division is only once.

There is a repetitive division.

It includes definite pattern of division.

It has no definite pattern of division.

It occurs only during favorable conditions.

It occurs during unfavorable conditions as well.

Both the Nucleus and cytoplasm divide simultaneously.

Nucleus division is followed by the cytoplasm.

Examples are Amoeba, Bacteria, Euglena, etc.

Examples are Plasmodium, Sporozoans, Algae, etc.
