Mitosis- comprised of 4 stages :prophase, metaphase, anaphase, telophase this process ensures that each new cell being made has a nucleus with the correct amount of chromosomes. Mitotic phase- Stage of the cell cycle where the cell's nucleus is dividedĬytokinesis- Stage of the cell where the cytoplasm is divided and two new daughters cells are formed G2- Gap phase 2, Stage of the cell cycle where the cell undergoes its final growth before division G1- Gap phase 1, Stage of the cell cycle where organelles are replicated S Phase- Synthesis phase Stage of the cell cycle, when DNA is replicated Interphase- The longest stage of the cell cycle main stages of growth and preparation for cell division. Another shared phase is Cytokinesis, where the cell divides and cytoplasm separates.Cell Cycle - The stages the cell go through as it grows and divides In Anaphase of mitosis and Anaphase I of meiosis, the sister chromatids are pulled apart by the mitotic spindle. In meiosis, however, Metaphase, Anaphase, and Telophase happen twice to produce four daughter cells.Īlthough the phases of replication vary for mitosis and meiosis, they share similar processes in Metaphase II, where chromosomes line up along the cell's equator. Both processes use Prophase, Metaphase, Anaphase, and Telophase. In both meiosis and mitosis, cell replication begins with a diploid parent cell, containing a full set of 46 chromosomes. As we previously went over, mitosis and meiosis both create new cells. Both processes occur in the cell’s nucleus and involve cell division. Uses Prophase, Metaphase, Anaphase, and Telophase (then transitions to Meiosis II)Ĭhromosomes line along the center of the cell in Metaphase IIĮnds with Cytokinesis, which divides the cell’s cytoplasm in halfĪlthough mitosis and meiosis are not the same, there are distinct similarities between the two processes. Occurs in the cell's nucleus, and breaks down the nuclear membrane. Uses Prophase, Metaphase, Anaphase, and TelophaseĬhromosomes line up along the meiotic plate in Metaphaseīoth end with Cytokinesis, which divides the cell’s cytoplasm in half Occurs in the cell's nucleus, and breaks down the nuclear membrane Amoeba reproduce by binary fission, in which the parent cell divides in half to form a new amoeba. One example of an organism that undergoes asexual reproduction is the amoeba. Some organisms reproduce asexually, which is a form of reproduction that only requires one parent. Mitosis occurs in all living organisms except for viruses, while meiosis only occurs in animals, plants, and fungi. For example, if a skin cell undergoes mitosis, it will produce identical skin cells, not hair or nerve cells. In contrast, mitosis only produces two genetically identical daughter cells. In meiosis, the result is four genetically diverse haploid daughter cells. Mitosis and meiosis have key differences that are important to distinguish! The most clear differences are the results of each process. Only undergoes Metaphase, Anaphase, and Telophase once Occurs in all living organisms (except viruses) Undergoes Metaphase II, Anaphase II, and Telophase II Only occurs in animals, plants, and fungi DNA is the information inside of a chromosome that determines an individual's traits.Ĭreates four genetically unique daughter cells. A chromatid is one half of a replicated chromosome. Here are some important definitions that will help you understand this topic:Ī chromosome is an organized assortment of DNA that is found in the nucleus of the cell. There is literally only one version of you! □ Two gametes virtually never have the same genetic makeup because there are 8,324,608 possible combinations of 23 chromosome pairs. Since meiosis produces cells used in reproduction, each daughter cell created is genetically diverse. Mitosis produces four haploid cells, meaning the cells have a set of 23 chromosomes. Males reproduce millions of sperm cells every day. Females reproduce ova cells once a month through a process called ovulation. In males, these sex cells are sperm cells for females, these sex cells are ova cells. Meiosis occurs when your body needs to reproduce sex cells, or gametes. Meiosis is a process of cell replication that produces four genetically diverse daughter cells.
