Question

what is fission? Define

Answer 1

An atom contains protons and neutrons in its central nucleus. In fission, the nucleus splits, either through radioactive decay or because it has been bombarded by other subatomic particles known as neutrinos. The resulting pieces have less combined mass than the original nucleus, with the missing mass converted into nuclear energy.

Answer 2

$\star$Fission : Fission means the division of single cell into two or multiple.

$\star$So, Fission are of two type:

1) Binary Fission

2) Multiple Fission

1) Binary Fission : In binary fission the cell or an Organism divide into parts (as in asexual reproduction)

e.g. : amoeba & paramecium

2) Multiple Fission : The division of single(or parent cell) into more .

e.g. : Planaria
