CheckPoint: Mitosis and Meiosis
Mitosis and meiosis are both important to a living organism because they represent cell divisions that are very important to every living organism because without cell division all living organisms would fail to reproduce, eventually dying out. Cell division plays a very important role in the life cycle of a cell. Mitosis and meiosis are important to living organism because they help living organisms to grow, develop, and reproduce. Mitosis is a type of asexual reproduction, which enables a cell to reproduce two new genetically identical daughter cells from a single parent cell. During the process, mitosis provides the necessary function of permitting cells to be replaced once they are worn out, damaged, or need to be replicated for single cell organism reproduction (Pruitt & Underwood, 2006). Meiosis is “the process by which certain sex cells are created” (Groleau, 2001). Meiosis occurs in a particular arrangement of one’s cells to create eggs and sperm. Meiosis involves the reproduction of two parent cells of a specific type to create four daughter cells, which have genetic material from both parent cells. Meiosis plays an important part in organism reproduction because it permits chromosomes of more complex organisms to be passed down from parent cells to daughter cells in a way that allows for an endless potential for genetic diversity.
An organism needs to undergo the process of mitosis to repair damaged cells or to start a new cell life cycle through cellular division. A cell need to be replaced on the regular basic within a living organism, the cells divide and create new cells. An organism would undergo the process of meiosis when it needs to produce cells designated for sexual reproduction, such as egg or sperm cells within humans. If meiosis did not occur, the reproduction of sex cells involving the combination of genetic information from two parent cells and the ability...
