Mar 14, · 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 Meiosis Essay Meiosis Words | 2 Pages Meiosis happens in a two-stage process of cell division that produces four haploid cells from one diploid cell. The process begins from a single dividing nucleus that is composed of two sets of replicated Dec 21, · Meiosis contained a diploid cell that has two copies of each chromosomes and it produces four haploid cells containing a copy of each chromosomes. Written by M. J. Farabee, Sexual reproduction occurs only in eukaryotes. Eukaryotes: Any of the single-celled or multicellular organisms whose cell contains a distinct, membrane-bound nucleus
Observing mitosis and meiosis on cell specimens essay sample - Essay Example for Words
Mitosis is a word from biology that means cell division. Another word, Meiosis, also comes from biology and means cell division. Cell is the basic unit and building block of all organisms. Cells have to meiosis essay because outside of the cell unable to keep up with the inside when the cell grows bigger. Cell division is conducive for the transportation of the food and oxygen to the cell. Although these two words are similar, when compared, the meiosis essay processes are totally different in purpose, occurrence, steps, and production. Differences Between Mitosis and Meiosis Essay Meiosis essay. In the daily life of all organisms or living things include the human; both of mitosis and meiosis play important role.
Nevertheless, each of them plays a different role. For mitosis, the purpose meiosis essay it, which is growth and maintenance or keep organism healthy. Conversely, the meiosis essay important role that meiosis plays is reproduce. As you know, growth and reproduce are two necessary factors help us to determine a thing is organism or not. In addition, different purpose decides they take place in different sort of cells. Usually, mitosis only occurs within somatic cells or body cells but meiosis take place within gamete cells or sex cells. In this case, a new word from genetics will be introduce, which called crossing-over. Crossing-over, meiosis essay, this word in genetics means the exchange of chromosome between homolog chromatids during meiosis. It only takes place within meiosis and usual occur before meiosis I.
After crossing-over, chromosomes are truly entering the process of meiosis. The whole process of meiosis divided meiosis essay 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, meiosis essay, meiosis essay 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, meiosis essay, meiosis essay 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, meiosis essay. 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, meiosis essay, 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, meiosis essay, they are completely different types of cell division.

Mitosis And Meiosis Essay Describe the processes of mitosis and meiosis in details and their functions Introduction Cell division does not stop with the formation of the mature organism but continues in certain tissues throughout life. It is because cell cannot grow any larger Meiosis Essay Meiosis – errors that occur Sexual reproduction is that the union of male and feminine gametes to create a fertilised egg or zygote. The ensuing offspring inherit one-half their traits from every parent. Consequently, they 're not genetically similar to either parent or siblings, except within the case of identical twins Apr 20, · Phases -- Meiosis: 1) Meiosis 1 -- separates chromosomes in half; DNA is exchanged and chromosomes coil and uncoil and share information; 2) Metaphase 1 -- Chromosomes align along an equatorial plane; 3) Anaphase 1 -- Kinetochore (bipolar spindles) shorten and pull the chromosomes apart; 4) Telophase 1 -- the chromosomes arrive at the
