Division in a bacterial cell is carried out through
multiple fission
binary fission
budding
plasmotomy
B.
binary fission
Division of bacterial cell is carried out by binary fission, in which, a single cell divides into two equal sized cells after developing a transverse cell wall.
Multiple fission is the division of the nucleus, simultaneously or successively into a number of daughter nuclei, followed by division of the cell body into an equal number of parts each containing a nucleus.
Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site.
Plasmotomy is a type of asexual reproduction in which a multi- nucleate protozoan cell divides into two or more multi- nucleate daughter cells without the occurence of mitosis.
