How does cell division take place

Question

anonymous · Answer

There are three kinds of cell division: mitosis, meiosis, and binary fission. Mitosis occurs when a eukaryotic organism needs to produce more cells, all genetically identical to the existing cell. It is therefore common in growth of multicellular organisms, and in asexual reproduction. Meiosis halves the chromosome number, usually from two sets (a diploid cell) to one (haploid). In humans this occurs in the formation of gametes, and so the only haploid cells in the human life cycle are the gametes. In some algae it is the zygote that divides by meiosis, with the result that the zygote is the only cell in the life cycle that is diploid. Meiosis is also important because all the daughter cells are genetically different. Binary fission is confined to bacteria. It produces two genetically identical cells.
