Write any two differences between binary fission and multiple fission in a tabular form as observed in cells of organisms.
Write any two differences between binary fission and multiple fission in a tabular form as observed in cells of organisms.
Official answer
The differences between binary fission and multiple fission are tabulated below:
| Feature | Binary Fission | Multiple Fission |
|---|---|---|
| Number of daughter cells | The parent cell divides/splits into two equal halves, producing two daughter cells. | The parent cell divides into many daughter cells simultaneously. |
| Examples | Amoeba, Leishmania, bacteria | Plasmodium (malarial parasite) |
Marking scheme
- 1.Correctly stating the difference in the number of daughter cells produced in binary vs multiple fission. (1 mark)
- 2.Providing correct examples for both types of fission (*Amoeba*/*Leishmania* for binary, *Plasmodium* for multiple). (1 mark)
Hint
Think about how many daughter cells are produced from a single parent cell in *Amoeba* compared to the malarial parasite *Plasmodium*.
Quick oral answer
In binary fission, a single cell splits into two equal halves, as seen in Amoeba. In multiple fission, a single cell divides into many daughter cells simultaneously, as seen in Plasmodium.
Common mistakes
- 1.Confusing the examples, such as writing Plasmodium for binary fission and Amoeba for multiple fission.
- 2.Not presenting the answer in a tabular format when specifically asked in the question.
Analysis and explanation
Binary fission and multiple fission are both asexual modes of reproduction occurring in unicellular organisms. The primary distinction lies in the number of offspring produced in a single reproductive cycle. In binary fission, the nucleus and cytoplasm divide once to produce two identical daughter cells. In multiple fission, the nucleus undergoes repeated divisions within a protective cyst to produce numerous nuclei, which then acquire cytoplasm and release many daughter cells at once when the cyst ruptures.
Interesting facts
While Amoeba can divide in any plane during binary fission, Leishmania has a whip-like structure (flagellum) at one end, which restricts its binary fission to a definite longitudinal orientation.
