Explain the types of binary fission with examples.
Answers
Explanation:
In biology, binary fission is a type of asexual reproduction where a parent cell divides, resulting in two identical cells, each having the potential to grow to the size of the original cell. ... Binary fission is common among prokaryotes, e.g. archaea, eubacteria, cyanobacteria, and certain protozoans (e.g. amoeba).
Types of binary fission :-
- There are 4 types of binary fission namely :
- Longitudinal Binary fission
- Transverse Binary fission
- Oblique Binary fission
- Irregular Binary fission
What is Binary fission :-
Binary fission is an asexual mode of reproduction with the involvement of a single parent. There is no fusion of gametes. The parent cell splits into two daughter cells. A clone is produced in this type of reproduction.
Longitudinal Binary fission :-
As the name suggests, the splitting takes place vertically/the longitudinal axis, occurring in Euglena.
Transverse Binary fission :-
The mode of Binary fission in which cytokinesis (the division of cytoplasm) occurs along the transverse axis. Example :- Scyphistoma polyps.
Oblique Binary fission :-
In this type of fission, the division does not occur in any certain way thus resulting in two irregular daughter cells. Example is that of a Paramecium.
Irregular Binary fission :-
Here, the cytokinesis (division of cytoplasm) division occurs along a perpendicular plane to that of a karyokinesis (division of the nucleus). Examples is that of an Amoeba.
