Mitosis and meiosis are both important parts of a living organism life because both play very specific function in growth and reproduction. These occur as the body grows and becomes able to reproduce. Mitosis is when an organism reproduces a new cell that is an exact copy of the original. All organisms start as one cell. In order for the organism to grow, mitosis must occur in order to duplicate this one cell to make more and more until cells fill the organism as it grows. These cells also replace old, dead or dying cells that will be discarded. The cells are all completely identical and contain the exact same number of chromosomes and are the same shape. Meiosis is similar to mitosis in that it reproduces cells only meiosis duplicates itself with half the number of chromosomes. This occurs by taking a diploid cell (a cell with the full number of chromosomes) and producing a haploid gamete (cell with only

Generally with the female egg, three of the four die do to the size being too small. With males, four sperm are duplicated. When the two are united they put both of their half chromosome cells together in order to form one cell that will then start the mitosis process. Without meiosis, the process of reproduction would simply not be possible. Reference: Higheredbcs. (). BioInquiries .
