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

    Mitosis is easily observed in cells that are growing at a rapid pace such as whitefish blastula or onion root tips, which was used in this lab experiment. The root tips contain and area called the apical meristem that has the highest percentage of cells undergoing mitosis. The whitefish blastula is formed directly after the egg is fertilized. This is a period of rapid growth and numerous cellular divisions where mitosis can be observed. In mitosis the cell is in interphase, and have a distinct nucleus and nucleoli where the thin threads of chromatin thicken into distinct chromosomes and the nuclear evvelope breaks open releasing them into the cytoplasm. The firs signs of the spindle begin to appear, next the cell begins metaphase, where the spindle attaches to the Centromere of each chromosome and moves them to the same level in the middle of the cell. This level position is called the metaphase plate. Anaphase begins when the chromatids are separated and pulled to opposite poles, then the final stage is telophase. The nuclear envelope is reformed and the chromosomes gradually uncoil. Cytokinesis may occur, in which, a cleavage furrow will form and the two daughter cells will separate. Meiosis is more complex and involves two nuclear divisions. The…

    5) Mitosis and meiosis are alike in the respect that go through most of the same phases, and are used for reproduction purposes. However, meiosis results in sexual reproduction, in order to create multicellular organisms, occurring in only animals, humans, fungi, and plants, whereas mitosis occurs in all organisms. Mitosis only goes through one division, has the same number of chromosomes, and creates only two diploid cells. Meiosis undergoes two divisions, the creation of four haploid cells, and half reduces the chromosomes.…

    Mitosis is needed to repair damaged cells or to start a new cycle through cellular division. The cells divide and will create new cells when a cell needs to be replaced on a regular basis within the living organism. If the living organism is aging mitosis can repair the older cells. There are hormones in the organism’s body that sends signals to the cells to prepare for division when it is needed. Interphase which is the growth, preparation, and cell division Pruitt and Underwood, 2006). Meiosis is needed to produce cells designed for sexual production. Without mitosis and meiosis simple organism could not reproduce and complex organism could not repair damaged cells, or contribute to DNA to offspring.…

    A: Mitosis is not for sex cells. Mitosis also uses RNA to replicate the DNA and divide. Meiosis is for sex cells (sperm and egg) and doesn't use RNA to replicate. They are similar in that they are the two main ways that cells divide to form more cells. Mitosis provides four cells and meiosis provides two cells.…

    2. In 2-4 sentences compare and contrast mitosis and meiosis including the steps, purpose and products. Mitosis and meiosis are types of nuclear division that make different types of cells. Mitosis makes diploid cells that are genetically identical. It takes place throughout an organism’s lifetime and is involved in asexual reproduction. During meiosis, diploid cells undergo 2 cell divisions that result in 4 haploid cells. Meiosis occurs in sex cells, produces gametes, increases genetic diversity and produces genetically unique cells. It takes place only at certain times in an organism’s life cycle and is involved in sexual reproduction.…

    DNA must replicate before mitosis or meiosis can occur. If daughter cells are to receive a full set of genetic information, a duplicate copy of DNA must be available. Before DNA replication occurs, each chromosome consists of a single long strand of DNA called a chromatid. When a diploid cell undergoes meiosis, four unique haploid daughter cells are produced. It is important for gametes to be haploid…

    Puppies increase in size as their cells grow and divide. Almost all cells complete a full cell cycle that includes interphase and cell division. In interphase, cells serve their specialized functions, grow, and copy their genetic material. Mitosis is the first stage of cell division, in which the copied chromosomes are separated into two new nuclei. Then in cytokinesis the cell divides into two daughter cells. If no mutations or errors occur, the genetic material in each daughter cell is identical to what was in the original cell.…
