Hiw does binary fusion differ from multiple fission
Answers
Binary fission: It involves the longitudinal or transverse splitting of an organism into two equal halves which develop into two separate individuals.
Binary fission is generally seen in unicellular organisms such as amoeba and paramecium..
Binary fission can also be observed in multicellular animals like sea anemones and planarians.
Multiple fission: Multiple fission is the process by which organisms reproduce under unfavourable conditions.Under unfavourable conditions, organism does not stop reproducing but divides rapidly inside a cyst and forms many individuals inside the cyst, when favourable conditions prevail, organism releases multiple individuals at the same time which are formed by multiple fission.
Multiple fission is the division of mother cell into many daughter cells simultaneously.
A multinucleate mass is formed with rich cytoplasm which does not undergo division until certain amount of time.
The specific reason behind the organism reproducing by multiple fission is that, it can divide itself into many cells at the same time inside the cyst during unfavourable conditions in the host.
In other words,
Binary fission: In binary fission, only 2 daughter cells are formed from the splitting of the parent cell. In multiple fission, many daughter cells are produced simultaneously from the parent cell.
In binary fission, the parent nucleus divides only once, forming 2 nuclei.This is followed by cytoplasmic division, resulting in formation of 2 daughter cells.
Multiple fission:
In multiple fission, the nucleus undergoes several divisions, producing a number of nuclei. After the nuclear divisions are complete, the cytoplasm separates, and each nucleus becomes encased in its own membrane to form an individual cell.

Binary fission Binary fi : Two daughter cells are produced from the single parent cell.It is splitting of single cell into two halves. It needs favourable conditions.Cytoplasm divide after each nuclear division .Example:Paramecium
Multiple fission: Two or multiple daughter cells are produced from the single parent cell.It can occur in unfavourable conditions also. Cytoplasm does not divide after each nuclear division .Example: Plasmodium and amoeba
