Images for Learning Mitosis: Cell Division Diagram
Cell Division Diagram - Mitosis is a process of cell division. In this process a cell divides itself into two same exact cells. Such process aims to reproduce and regenerate a new cell. It is meant to repair a damaged cell or tissue in the body. It is also as a process of impeding the aging process. Mitosis generates two new identical cells which will replace the damaged cells. There four stages of mitosis or cell division.
Stages of cell division diagram
As told before, the stages of Mitosis are four. They are prophase, metaphase, anaphase, and telophase. Before talking about the mitosis process and stages, we will discuss how mitosis happens. Mitosis is proceeded with the happening of interphase process. With interphase happens, it then proceeds to mitosis process. So, what is interphase?
Well, interphase is a process when chromatin produces chromosomes. The existence of chromosomes is what makes mitosis and its stages possible. Next, we go on with the stages of mitosis. The first stage of mitosis is prophase. In prophase stage, chromatin condenses and becomes chromosomes. Nuclear envelope, nucleolus, cytosol, plasma membrane, centromere, chromosomes are involved in this prophase stage.
Then, the next process is nucleus disappears. The nucleus cover or envelope also disappears. Next, there forms what is called as centrosomes and these centrosomes later form miotic spindle.
The next stage after prophase is metaphase. There is characteristic of this stage. That is metaphase plate. At the center of miotic spindle, metaphase plate covers the microtubules. This metaphase plate is actually formed by chromatid pairs which are inside the centromeres.
Thirdly, in the anaphase stage, chromatid pairs separate themselves. These chromatid pairs are divided by centromeres. During the anaphase stage, microtubules pull the chromosomes. This process makes ‘V’ shape. V shape is formed by the dragging process of the chromosomes to the poles.
The last stage of mitosis is telophase. In the telophase step, the movement of chromosomes stop and the two identical chromosomes become a chromatin-like. A new nuclear forms which shapes like an envelope. It covers the chromatin. Through this step, nucleoli come out and the miotic spindle divides itself. These four stages are repeated themselves again and again. Thus, those stages show us how cell division diagram do the cycle.
