Methods of Asexual Reproduction

Methods of Asexual Reproduction :
Multiple Fission :
In multiple fission, many individuals are formed from a single individual.

The nucleus of cell divides repeatedly, producing many nuclei.
Each nucleus is surrounded by a small amount of cytoplasm & many daughter cells are produced within the cyst.
The cyst breaks up under favourable conditions & small off springs are liberated.
In plant, multiple fission is seen in many algae & in animals, a common example of multiple fission is that of the malarial parasite (Plasmodium).
Budding :
In budding a small part of the body of the parent organism grows out as a ''bud'' which then detaches and become new organism.
The nucleus of the parent divides and one of the daughter nuclei passes into the bud.
The bud detaches itself from the parent body & becomes a new individual after growing to full size.
In plants, budding takes place in yeast and in animals budding is seen in hydra & sponges.
