The Microscopic Identification of the Phases of Mitosis Using Onion Root Tip Cells
Lauren Harvey and Jason Levigne
Background:
Mitosis is part one of the Mitotic Phase. The overall outcome the Mitotic Phase is taking one diploid cell (2n) and splitting it into two diploid (2n) cells. The Mitotic Phase includes two parts: Mitosis and Cytokinesis. The main goal of the Mitotic Phase is to achieve two things, both division of the genetic nuclear material, otherwise known as DNA, and the division of the cytoplasm. Once these requirements are all met, the Mitotic Phase will have successfully completed in making one diploid cell into two diploid cells. The first step of the Mitotic Phase is Mitosis, Mitosis too has parts that make it up. The process …show more content…
Once cells are successfully checked and prepped in Interphase, the cell continues into the first part of the Mitosis. In Prophase, the chromosomes will coil up and the nucleus and nucleolus will disappear. The next phase of Mitosis is Metaphase, in metaphase the newly-created chromosomes will line up along the metaphase plate or the equator of the cell. The phase of Mitosis following Metaphase is Anaphase. In Anaphase those perfectly aligned chromosomes created in Metaphase, will now split. The final phase of Mitosis is Telophase. In telophase the chromosomes will uncoil and the nuclear membrane with nucleolus that disappeared in Prophase, will reappear in in Telophase. Now onto the next part of the Mitotic Phase, Cytokinesis. At the end of Telophase, Cytokinesis will appear finalizing the splitting of the diploid cell into two identical diploid cells. According to research, the process of Mitosis, excluding Interphase, takes about seven-and-a half hours to complete Mitosis in an Allium cepa. The time for Prophase was 180 minutes, 128.2 minutes to complete Metaphase, a total of 77.8 minutes for Anaphase, and 51.2 minutes for Telophase (The Regents of the University of California and Monterey Institute for Technology and …show more content…
Cells are the basic unit of life and every single living thing is made of cells. Therefore, without cells one could not possibly exist. Every time one touches something, swallow, etc. that person loses cells, which are necessary to keep that person alive. If one is constantly losing cells, and cells are what we are consisted of, if one always loses cells but never gains them that person will eventually lose all of their cells which one needs to function, and would die. However, we are still here, because of the process of Mitosis. When a person loses cells, Mitosis works hard to help produce more cells so that person can remain healthy and alive. Aside from without mitosis we wouldn’t exist, mitosis also helps with healing wounds. When a person skins a knee or gets a cut on their hand, that person would lose cells. If Mitosis didn’t exist our wounds would be open for forever. If a wound is open forever, one would constantly lose blood, more cells, and their wound could potentially get infected. However, since Mitosis does exist our knees and hands are able to heal due to the replacement of those missing cells that we lost when we injured ourselves. Therefore Mitosis which repairs, develops, and grows new cells is relevant and much needed because Mitosis keeps us alive and well.
