Meiosis is a key event of the sexual cycle in Eukaryotes. It is the stage of the life cycle when a cell gives rise to two haploid cells (gametes) each having half as many chromosomes. Two such haploid gametes, arising from different individual organisms, fuse by the process of fertilization, thus completing the sexual cycle. Meiosis is ubiquitous among eukaryotes.
Mitosis is the part of cell division in which replicated DNA is separated into the two halves of a dividing cell. Eukaryotes are organisms which have cells containing membrane-bound compartments called organelles, such as the nucleus and mitochondria. Prokaryotes, on the other hand, do not have such compartments.
