Binary Fission: Different Types of Binary Fission, Irregular Binary Fission
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
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. |
