14.+Mitosis

__Mitosis__
Mitosis is a type of cell division (when a cell divides and makes multiple copies of itself).

The process of mitosis plays an important role in both unicellular and multicellular organisms. In unicellular organisms, mitosis is needed for reproduction. It is how the organisms reproduce. In multicellular organisms, mitosis is needed for growth and repair. Without mitosis you could not grow from a baby into an adult. If you cut yourself, you need mitosis to repair the cut and grow new tissue. media type="youtube" key="zrx7Xg0gkQ4" height="315" width="420"

The process of mitosis happens in several steps. First each cell makes a duplicate copy of its chromosomes (DNA). Then the two sets of chromosomes are separated. At this point it is as if the cell has two nuclei (plural of nucleus). Then the cell divides into two smaller cells. The cells grow bigger then the whole process starts again.
