How do cell differentiation and cell division work together?
Flura [38]

Answer:

After mitosis is over, each of the daughter cells continues its separate life.

Explanation:

One or both can be started or continued through differentiation, ie. processes that give different cells special structures and functions. A cell destined to become a nerve cell moves in one way of differentiation, and a cell destined to be a muscle cell moves in another.

A variation of this mechanism involves a special type of cell called a stem cell. The stem cell divides by mitosis, whereby one daughter cell remains the stem cell and continues to divide again and again, while the other difference in certain cell peaks is determined in the tissues.
