What is the Difference Between Binary Fission and Multiple Fission?

🆚 Go to Comparative Table 🆚

Binary fission and multiple fission are both asexual reproduction methods in which a single parent cell divides to produce two or more daughter cells. However, there are some key differences between the two processes:

  1. Number of daughter cells: In binary fission, a single parent cell divides into two daughter cells, while in multiple fission, a single parent cell divides into many daughter cells.
  2. Fusion of cytoplasm and nucleus: In binary fission, both the cytoplasm and nucleus divide together, whereas in multiple fission, the nucleus divides first and is surrounded by cytoplasm, whose division occurs later.
  3. Conditions: Binary fission occurs during favorable conditions, while multiple fission takes place during unfavorable conditions, such as the formation of internal cysts.
  4. Pattern of division: Binary fission has a definite pattern of division, while multiple fission does not.
  5. Examples: Binary fission is observed in organisms like bacteria and amoebae, while multiple fission is common in protists and parasitic species, such as Plasmodium and algae.

Comparative Table: Binary Fission vs Multiple Fission

Here is a table comparing binary fission and multiple fission:

Characteristic Binary Fission Multiple Fission
Number of daughter cells 2 Many
Division process Single Repeated
Division pattern Defined Not defined
Conditions Favorable Unfavorable
Nuclear division Immediately followed by cytoplasmic division Not immediately followed by cytoplasmic division
Number of divisions One time Multiple times
  • In binary fission, a single cell divides into two genetically identical daughter cells. This process occurs in favorable conditions and is commonly observed in prokaryotes.

  • In multiple fission, a single cell divides into many daughter cells simultaneously. This process occurs in unfavorable conditions and is commonly observed in protists and parasitic species.
