How does binary fission differ from multiple fission?
Hint: They vary based on the number of divisions in the parent cell. Fission may lead to two identical portions or several identical portions. Thus, fission can be classified as either binary fission or multiple fission.
Complete Answer:
Fission is a type of asexual reproduction observed in Archaea, Bacteria, and various other single-celled organisms. This process involves dividing a single cell or organism into two or more segments, each capable of developing into a new individual that resembles the original parent cell or organism.

Binary fission |
Multiple fission |
| 1. | In binary fission, the parent cell splits into two offspring cells. | In multiple fission, the parent cell splits into multiple offspring cells. |
| 2. | This type of fission occurs in favorable conditions. | This type of fission occurs in unfavorable conditions. |
| 3. | In binary fission, division happens once. | In multiple fission, division happens repeatedly. |
| 4. | In binary fission, both the cytoplasm and nucleus divide at the same time. | In multiple fission, the nucleus divides first, followed by the cytoplasm. |
| 5. | Examples include Euglena and Amoeba. | Examples include Algae and Plasmodium. |
Note: In binary fission, an organism splits longitudinally or transversely into two equal parts, each developing into a separate individual.
– Under adverse conditions, the parent cell continues reproducing and rapidly divides within a protective cyst, forming numerous cells inside.
– When conditions become favorable, the parent cell releases several daughter cells simultaneously, which were produced through multiple fission.
