Mitotic Cell Division
2016-10-04 11:23:35 · answer #2 · answered by ? 4 · 0⤊ 0⤋
Mitosis is preceded by an exact duplication of the DNA and associated proteins in the nucleus. This occurs during interphase—the period between actual mitotic divisions. After this doubling, the chromosomes are organized, complete division and are then equally distributed to the two daughter cells during mitosis.
All somatic cells pass through the mitotic and interphase periods at one time or another. The duration of the mitotic period is usually about 0.5 to 2 hours, while the intermitotic period can vary from a few hours to many years. The mitotic index (proportion of cells undergoing division at any one time) varies greatly depending upon the type of tissue and the physiological needs of the organism. A high mitotic index characterizes all growing embryonic tissues, and certain adult tissues such as bone marrow and intestinal crypts as well as cancer cells.
We will study Cell Division during the G.I lab since the crypts of the small intestine are a convenient place to find mitotic cells. The student should learn to recognize and roughly estimate the number of mitotic figures normally seen in various tissues. Later, when pathological tissue is examined, the number of mitotic figures can give important clues to the type of disease.

RE:
what is the importance of mitotic cell division?

Ok if you are looking for a slightly more simple answer, lol, the importance of mitotic cell division is:
it produces two daughter cells per division that are not only genetically identical to each other, but also to the parent cell.
which therefore allows for growth and repair of tissue.

WIthout mitotic cell division, we would not be alive today. This process begins from the moment we are conceived and continues with us until the day we die. Without it, we would never heal, or grow, or replenish ourselves. There is, of course, alot more to it than that, and I suggest you read about it, it's quite interesting.

It allows cells to divide while retaining all information coded in their DNA.

without this kind of division,even no fertilisation will take place

without them, there will be no growth, and eventually no life at all.
