Distinctions Between Meiosis and Mitosis
Mitosis is a word from biology that indicates cell department. Another word, Meiosis, likewise comes from biology and means cell division. Cell is the basic unit and building block of all organisms. Cells have to divide due to the fact that outside of the cell not able to stay up to date with the within when the cell grows bigger. Cell department contributes for the transportation of the food and oxygen to the cell. Although these 2 words are similar, when compared, the actual processes are absolutely different in function, event, actions, and production.

In the every day life of all organisms or living things include the human; both of mitosis and meiosis play important role. Nonetheless, each of them plays a different role. For mitosis, the purpose of it, which is growth and upkeep or keep organism healthy. Alternatively, the most essential function that meiosis plays is reproduce.

As you understand, development and replicate are 2 required factors help us to determine a thing is organism or not.

In addition, different purpose decides they occur in different sort of cells. Normally, mitosis just occurs within somatic cells or body cells however meiosis occur within gamete cells or sex cells. Here, individuals can ask a question "What make cell division of a normal cell and a sex cell different. In this case, a new word from genetics will be introduce, which called crossing-over. Crossing-over, this word in genetics suggests the exchange of chromosome in between homolog chromatids throughout meiosis.

It only takes place within meiosis and normal take place before meiosis I. Furthermore, because it mixes chromosomes, it can explain why you have both of your moms and dads' genes. After crossing-over, chromosomes are genuinely getting in the procedure of meiosis.

The whole process of meiosis divided two sections- meiosis I and meiosis II. More specifically, meiosis I divided to prophase 1, metaphase 1, anaphase 1, and telophase 1. Meiosis II also includes prophase 2, metaphase 2, anaphase2, and telophase 2. On the other hands, mitosis is easier, which only divide to four phases: prophase, metaphase, anaphase, and telophase. During prophase, chromosomes appear. Then, the process of metaphase is chromosomes line up the middle. And anaphase makes sister chromosomes separate. After telophase, two new nuclear membrane form. The last step of normal cell division is cytokinesis. However, it is the cytoplasm divided to half and it was not included by mitosis. After all of these phases, mitosis and meiosis will produce new cells. The difference of the products is mitosis produces 2 diploid (genetically identical) cells but the outcomes of meiosis are 4 haploid (genetically unique) cells. That is why the function of mitosis is growth and the function of meiosis is reproduce.

By comparing, we know mitosis and meiosis are dissimilar sorts of cell division. Especially in their purpose, steps, occurrence, and production. In particular, meiosis occur crossing-over, which is a very specific step of cell division. Therefore，we have every reason to believe that although as words, meiosis and mitosis are similar, as well as the fact they are both essential to the body, they are completely different types of cell division.
