Asexual mode of reproduction is a way to reproduce offsprings adapted by the majority of simple organisms. In asexual mode of reproduction the formation of gamete is not required. In this only a single parent is involved,  which either breaks down or produce precursor of the offspring. Examples, of asexual reproduction includes budding, binary fission, fragmentation and sporulation.

In budding a small bud develops over a parent cell or organism which detach on maturity and germinate to form a new organism.

In binary fission a parent cell splits into two daughter cells with the equal distribution of genome in each cell.

In fragmentation a parent cell splits into more than one part and new organisms regenerate from the fragmented parts.

In sporulation numerous spores are released from a sporophyte. These spores germinate to form a new organism under favorable conditions.

In vegetative propagation, the buds, bulbs, tubers, stems and leaves and other plant parts are grown in a medium which can support the growth and development of a new plant.
