Fission - Asexual Reproduction

In this process the organisms divide mitotically into two or more equal sized parts. Division of the organism into two daughter cells is known as binary fission, which is characteristics of protozoans. The daughter organisms produced carry all the cytoplasmic organelles of the parent individual.

They also carry the same genetic material as found in the parent organisms. Some organelles like mitochondria divide at the time of division, while others like flagella and contractile vacuoles arc formed afresh by the daughter organisms. Protozoans at certain times also exhibit sexual reproduction. Their gametes are produced meiotically and mating takes place. In the following subsection you shall read about sexual reproduction in protozoans.
