Why is mitosis important?

Ahhh... finally a question I can answer! LOL. Well mitosis is EXTREMELY important because when we are first made(when the egg and sperm combine) we are only one cell. Mitosis is the process of interphase, prophase, metaphase, anaphase, telaphase, and cytokinesis. Basically it is the process of a cell dividing. If our cells never divided, then we would never be born. For example, we have trillions and trillions of cells, even though we started from only one. You see, when you start out as one cell, you have no nothing. No ears, no eyes, just a small blob in existence. Then mitosis happens; that one cell that is you is pulled apart into two cells. Then those two cells are each pulled in two. Then those two, and those two, and so on and so on. Your cells never truly stop dividing until you are fully grown. So in conclusion, if our cells never divided, then we would still be just one lone cell.
