During mitosis phase of cell division, one cell divides once to form two identical daughter cells. Mitosis is important for the following reasons: development and growth of a cell, cell replacement, repair, and asexual reproduction. Mitosis when occurs infinitely, can lead to cancer.

Meiosis is a type of cell division in which chromosome number are reduced to half in daughter cell cell as compared with that of parent cell. Thus, after meiosis, four haploid gamete cells are produced. This process is required to produce egg and sperm cells for sexual reproduction. Two main functions of meiosis are to halve the DNA content and to reshuffle the genetic content of the organism to generate genetic diversity or variations among the progeny.
