Question

How does binary fission differ from multiple fission?

Answer 1

Hint: They differ in the number of parent cell divisions. Two identical parts or more identical parts may result from fission. Fission, therefore, may be binary fission or multiple fission.

Complete Answer:
Fission is a process of asexual reproduction seen in Archaea, Bacteria, and some other single cell organisms. It is the method of splitting a single cell or an organism into two or more divisions which have the ability to regenerate into a new individual that is similar to a parent cell or organism.

Sl.No	Binary fission	Multiple fission
1.	In binary fission, the parent cell is divided into two daughter cells.	In multiple fissions, the parent cell is divided into many daughter cells.
2.	In this fission, the division takes place in favorable conditions.	In this fission, the division takes place in unfavourable conditions.
3.	In binary fission, division occurs one time.	In multiple fission, division occurs repeatedly.
4.	In binary fission, both cytoplasm and nucleus divide simultaneously.	In multiple fission, the nucleus divides first.
5.	Euglena, Amoeba are examples.	Algae, Plasmodium are the examples.

Note: The longitudinal or transverse dividing of an organism into two equal halves that grow into two distinct individuals involved in binary fission.
- Under unfavorable circumstances, the parent cell does not stop reproducing but rapidly divides in a cyst and creates many cells inside the cyst.
- When favorable conditions exist, the parent cell releases multiple daughter cells that are formed by multiple fission at the same time.
