Meiosis is a necessary step to ensure that the number of chromosomes is correct in organisms that reproduce sexually.
If it didn't occur, then every time two gametes fused the genetic material would double.
Bacteria and prokaryotes multiply by binary fission; the cell grows, DNA replicates and then the "big" cell divides into two cells of "normal" size. There is no need for meiosis.

They undergo binary fission which is a simple cell division and the DNA replicates itself

They do not have a well organized nuleus.Their nuleus like structure is known as nucleoid.Crossing over of chromosomes ,chromosmal interchange are not posible becuase of their primitive nucleus .They unergo asexual repoduction.Prokaryotes undergo amitosis----------.bacteria undergo fission-----

meiosis?
I don't think so.. I looked up the biology textbook and it said they undergo asexual reproduction

no dear, I'm damn sure they do not undergo meiosis & not even mitosis
