It is the reproduction of off springs from single organism without the use of sex cells (gametes).
It means that there is no fusion of gametes. Single celled organism like amoeba and bacteria use asexual reproduction as the only means of reproduction
There is different forms/methods of asexual reproduction depending on the type of organisms. Asexual reproduction may be of different forms such as
Binary
Fragmentation
Multiple fission(sporulation)
Budding
Suckers
Artificial/ Vegetative propagation
1) BINARY FUSSION (SPLITTING)
Is the process whereby organism divided into two (2) equally parts and each part then grows to attain the original size of the parent cell and becomes a separate and independent organism. Organism such as amoeba, paramecium euglena and trypanosome practice binary fission
