Question

The nucleus of parent divides by repeated amitosis into many nuclei, each nucleus takes a bit of cytoplasm and forms a daughter cell. This process is called -

• A. Spore formation
• B. Multiple fission
• C. Binary fission
• D. Budding

Answer 1

The correct option is B

Multiple fission

Amitosis is a simple method of cell division which occurs without formation of spindle fibres and appearance of chromosomes. Amitosis is also referred to as Binary fission and multiple fission.
Multiple fission - In multiple fission the nucleus divides several times simultaneously or successively into a number of daughter nuclei and then the cytoplasm divides into as many cells as there are nuclei, each cell containing a nucleus.
Budding is a form of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site.
Spore formation - A mode of reproduction resembling multiple fission, common among Protozoa, in which the organism breaks up into a number of pieces, or spores, each of which eventually develops into an organism like the parent form.
