Mitosis and meiosis Mitosis occurs all the time in all body cells. This occurs to produce new cells and replace old and dead cells. We produce new blood cells, bone cells, skin cells. ..the list can go on and on. Mitosis in a nutshell is the process of splitting the nucleus and it occurs hand in hand with the rest of the cell cycle and cytokenesis. Meiosis, on the other hand, is a process of taking a diploid cell (a cell with the full number of chromosomes) and producing haploid gametes (cells with only half the number of chromosomes). Meiosis occurs to produce sperm and egg cells which then can combine to produce the

Unformatted text preview: diploid zygote. If meiosis did not occur organisms that reproduce sexually could not produce new offspring. An organism would need to undergo mitosis for:-Growth-Development-Repair-Asexual reproduction Keep in mind that when prokaryotes such as bacterium reproduce, it is not through the process of mitosis. It is through binary fission, a type of asexual reproduction that produces identical offspring. Only eukaryotes go through the specific process of mitosis. A eukaryotic organism would undergo meiosis for:-Production of gametes (the organism's reproductive cells) for sexual reproduction....
