What are the functions of Mitotic Cell Division?
The main functions of mitosis are growth and repair. Some cells once fully formed do not undergo cell division, such as nerve cells and muscle cells. Since you can never re-grow or repair these types of cells once they are mature, you must take care of the ones you have. The process of mitotic cell division in eukaryotic cells is important for two main reasons: because cell division creates new cells that keep eukaryotic organisms thriving, and because cell division passes a consistent genetic identity to a new generation of cells.

Mitosis is the type of division that gives rise to daughter cells for the purpose of tissue growth, regeneration or asexual vegetative reproduction. After mitosis and cytokinesis the daughter cells contain the same information for properties for fuhction as the mothercell they are genetically identical.
The main functions of functiom are how to add a song to video and repair. Some cells once fully formed do not undergo cell division, such as nerve cells and muscle cells. Since you can never re-grow or repair these types of cells once they are mature, you must take care of the ones you have. However, to grow qhat size from a baby to teen-ager, all of the cells must undergo cell division.
This is true of an elephant or a human. As for repair, we all cut ourselves from time to time, and the cells along the edges of the cut undergo mitosis to repair the cut. The same is true of broken bones. The cells along the edges of the break undergo mitosis to repair the break. Generally, the functions of mitotic cell division are: 1 Mitosis maintains the same number of chromosomes in all its daughter cells. Or you could just say, 1 To form new somatic cells. Mitosis ensures that the daughter cells are identical to each other and lf the parent cell.
Therefore, it ensures the maintenance of the chromosome set. Hence, in this light, one of the primary functions of mitosis is growth. It allows functionn organism to grow and to develop by continuously dividing and producing new cells which are all identical to each other.
One of the common examples you could take is in the root tip of a plant. The cells divide continuously by mitosis and hence the roots grow in length as well as the plant. The same concept is applicable for growth in human beings. The second important si of mitosis is the repair function.
This is best illustrated using an example functuon to human beings. When there is an open wound, the neighboring cells will divide by mitosis to repair the damaged skin. This of course occurs after the formation of the clot and it is divisjon new cells which you can see as white smooth skin when your wound is healed.

Dec 05, · Mitosis is the phase of the cell cycle where the nucleus of a cell is divided into two nuclei with an equal amount of genetic material in both the daughter nuclei. It succeeds the G2 phase and is succeeded by cytoplasmic division after the separation of the nucleus. Mitosis is essential for the growth of the cells and the replacement of worn-out. Sep 14, · Generally, the functions of mitotic cell division are: 1) Mitosis maintains the same number of chromosomes in all its daughter cells. 2) Mitosis ensures that .
General Education. Mitosis is part of the cell cycle, and studying how cells work makes up a huge portion of any biology class.
We will:. Mitosis alternates with interphase to make up the cell cycle in its entirety. In fact, a cell cannot begin mitosis until interphase is successfully completed.
You may have heard about two types of cells: eukaryotic animal cells , and prokaryotic plant cells. Both types of cells undergo cell division, but only eukaryotic cells experience cell division through mitosis.
In fact, all eukaryotic cells can engage in mitosis. Mitosis happens exclusively in eukaryotic cells because this type of cell has a nucleus. In order to replicate the genetic material, mitosis has to occur in cells that have a nucleus. The dead cells need to be replaced with new cells so the organism can continue growing.
Second, the process of mitosis is so important because parent and daughter cells in certain types of organisms must be identical in order for the organism to survive. When mitosis occurs successfully, two new cells with the same genetic composition and an identical chromosome set to the previous generation are created. A period called interphase precedes mitosis in the cell cycle, and interphase and mitosis alternate as the cell cycle occurs over and over.
So, mitosis is the second or concluding part of the cell cycle, and mitosis cannot start until interphase has been successfully completed. During interphase, the cell grows and develops the proteins needed for cell division.
In the middle of the interphase period, the cell duplicates its chromosomes. Once the chromosomes have been duplicated and all other conditions are ideal in the cell, the first phase of mitosis can begin! We have a much longer article that covers the four phases of mitosis in more detail, but we do want to give you an overview of what the four phases of mitosis are and what happens during each phase here.
Mitosis is a process that happens in phases that always occur in the same order and accomplish the same tasks unless something goes wrong! The four phases of mitosis are prophase P , metaphase M , anaphase A , and telophase T. Each of these phases helps achieve the purpose of mitosis by moving the process of cell division and reproduction along. As the chromosomes condense inside the nucleus and the nuclear membrane disintegrates, centrioles outside of the nucleus start moving toward opposite sides of the cell and form the mitotic spindle , which is made up of fibers called microtubules.
The mitotic spindle stretches from one side of the cell to the other, suspended between those centrioles that moved away from each other. Metaphase is the second phase of mitosis. During metaphase, spindle fibers attach to the centromere of each pair of sister chromatids. The sister chromatids also move into the middle of the cell and line up along an invisible line, called the metaphase plate.
These spindle fibers prepare the sister chromatids to separate properly in the next phase of mitosis. Anaphase is the third phase of mitosis, and this is when cell division really begins.
During anaphase, the spindle fibers attached to the sister chromatids start shortening, which pulls the sister chromatids apart down the middle toward opposite sides of the cell. By the end of anaphase, each side of the cell has a complete, identical set of chromosomes. Finally, we have telophase: the fourth and final phase of mitosis.
In telophase, the separated chromosomes start to unfold and form chromatin. The spindle also disintegrates, and a new nuclear envelope forms around the two new sets of chromosomes. These two new sets of chromosomes make up two nuclei, which have received genetic information from their parent cell.
Mitosis, meiosis. You probably know that both of these processes have something to do with cells. Meiosis is also a form of cell division and reproduction! But while mitosis results in two identical daughter cells, meiosis results in four sex cells.
Here are the key differences between mitosis and meiosis as processes of cell division and reproduction:. But there are also several similarities between the processes of mitosis and meiosis.
Here they are:. Both mitosis and meiosis begin with a diploid parent cell, or a parent cell with two sets of chromosomes. Mitosis and meiosis go through the same phases, in the same order—prophase, metaphase, anaphase, and telophase—but the phases occur only once during mitosis and twice during meiosis.
Both mitosis and meiosis end with cytokinesis , the cytoplasmic division of a eukaryotic cell into two daughter cells. In general, you want to try to remember the two main differences between mitosis and meiosis: meiosis involves two cell divisions, while mitosis only involves one, and meiosis gives rise to the production of germ cells , while mitosis gives rise to the production of somatic cells.
Check out our top three tips for studying and memorizing the key details about mitosis below. Mnemonic devices are techniques that people can use to help them remember something. If you need to remember the 4 stages of mitosis in order, try memorizing one of these mnemonic devices:.
Get it? The first letter of each word in the mnemonic devices above corresponds with the first letter of each of the phases of mitosis, plus interphase:.
Adding one of these easy-to-remember phrases to your study arsenal can make remembering the phases of mitosis much easier in a high-pressure situation! Now for meiosis—and this one is easier. Maybe you need a trick to remember what happens during each phase of mitosis in addition to remembering what order they go in.
Prepare - middle - apart - tear. The idea with this one is to use one word that sort of sums up what happens in each phase of mitosis to trigger your memory about the other details of what happens in that phase. If a visual representation of what happens during each phase of mitosis is more helpful to you than another mnemonic device, try memorizing the quick hand trick demonstrated in this YouTube video!
You could also combine the descriptive words from the mnemonic above with the hand trick for a double whammy. One of the best places you can turn for that is Nature, an international science journal, and one of the most reputable in its field. The big drawback of most academic research journals is that the subscription fees are hefty.
If a full-fledged, peer-reviewed scientific journal is a bit much for you at this point, Nature Education provides a tapered down resource for students looking for credible overviews of science-related topics, called Scitable. Scitable focuses specifically on key genetic concepts, so they definitely provide content that covers mitosis.
When you search a concept on Scitable, the results pop up conveniently categorized based on type of content.
Their content is lively, accessible, and relatable, which is always a welcome way to learn more about or frantically review science-y things! Meiosis: Side by Side Comparison.
