Question

Answer

Hiiii

Binary Fission :
(i) Nucleus divides into two parts.
(ii) It occurs during normal conditions.
(iii) It gives rise to two individuals.
(iv) Cytoplasm divides after each nuclear division.
e.g., Amoeba.

Multiple Fission :
(i) Nucleus divides into many parts.
(ii) It takes place during unfavourable conditions (Encysted stage),
(iii) It forms many individuals.
(iv) Cytoplasm does not divide after every nuciear division.
e.g., Plasmodium.

Differences between Binary Fission and Multiple Fissions

Binary fission and multiple fissions are two distinct methods of asexual reproduction that are commonly observed in various organisms. While they both involve the division of a parent cell to produce new offspring, there are several key differences between these two processes.

1. Definition
Binary fission is a form of asexual reproduction in which a single parent cell divides into two identical daughter cells. On the other hand, multiple fission refers to a type of asexual reproduction in which a parent cell divides into multiple daughter cells simultaneously.

2. Number of Daughter Cells
Binary fission results in the formation of two daughter cells that are genetically identical to the parent cell. These daughter cells are separate entities that can function independently. In contrast, multiple fission leads to the production of multiple daughter cells. The number of daughter cells formed during multiple fission may vary depending on the organism, but it is typically more than two.

3. Process and Mechanism
Binary fission involves a series of steps that include DNA replication, elongation, and separation of the parent cell into two daughter cells. The process begins with the replication of the genetic material, followed by the elongation of the cell and the division of cytoplasmic contents. Finally, the cell membrane and cell wall divide, resulting in the formation of two daughter cells.

Multiple fission, on the other hand, involves a different mechanism. The parent cell undergoes repeated divisions, forming multiple nuclei within a single cytoplasm. Subsequently, the cytoplasm divides, and each nucleus is enclosed by a portion of the cytoplasm. This results in the formation of multiple daughter cells, each containing a single nucleus and a portion of the cytoplasm.

In summary, while both binary fission and multiple fissions are methods of asexual reproduction, they differ in terms of the number of daughter cells produced and the mechanism involved. Binary fission leads to the formation of two daughter cells, while multiple fission results in the production of multiple daughter cells. The process and mechanism of these two types of fission also vary, with binary fission involving a sequential division of a single cell, and multiple fission involving repeated divisions within a single cytoplasm.
