Fission is of two types Binary fission and multiple fission.

 

Binary Fission

It is the division of one cell into two similar cells.

Here the nucleus first divides amitotically into two, followed by the division of the cytoplasm.

The cell finally splits into two daughter cells.

Examples are

bacteria, yeast and Euglena. Amoeba and Paramecium also reproduce through binary fission.

 

 

Multiple Fission

In this method, many individuals are formed from a single individual.

The nucleus of the cell divides repeatedly hence producing many nuclei.

Each nucleus is surrounded by a small amount of cytoplasm and many daughter cells are produced within the cyst.

The cyst breaks up under favorable conditions and small offspring are liberated.

In plants, multiple fission is seen in many algae and in animals, a common example of multiple fission is that of the malarial parasite (Plasmodium).
