Answer:
The importance of mitosis lies in its condition of cellular reproduction par excellence, characteristic of the vast majority of life forms that currently populate the Earth.
Explanation:
Mitosis is the cellular process by which two identical nuclei are produced in preparation for cell division. In general, mitosis is immediately followed by the equitable distribution of the cell nucleus as well as the rest of the cellular content in two daughter cells.
We all start being a cell. That is quite difficult to imagine, but it is true. And now there are about a hundred billion cells in each of our bodies, and each one has to carry the complete set of DNA instructions. That means that when cells divide, all that has to be copied by some process. And that is mitosis, where each chromosome has to be converted into a pair, and then they have to separate properly so that each of the daughter cells receives a complete set.
It is the process of synthesizing new glucose.
