Cell division is basically reproduction of cells. Cell growth is when "the mother cell" grows and divides into two or more "daughter cells". Only the mother cell can reproduce like this. In mitosis, daughter cells are identical. In meiosis, daughter cells are genetically different. Cell division is the production of more and more cells.
Before cells can divide they make a copy of there deoxyribonucleic acid (DNA). The DNA of a cell is organized into structures called chromosomes. By copying these chromosomes it without a doubt makes sure it is and exact 100% copy of its parents cell. Cell division in bacteria is called binary fission. It means "splitting into two parts". Binary fission is where the mother cell grows and breaks apart to make two cells which is called cell division. This process helps children grow because of the fact of when that happens one time it happens twice the next time the four and so on which gives the kid more cells, but it all starts with that one mother cell.
We need this because everyday cell in our body die but other cells reproduce so we will always have cells. Also because we need cells to survive. Since if we don’t have living cells we don’t have living body parts. In order for the body parts to work the cells must work it is like the screw must stay in the wall for the picture to stay on it. It is all simple once you understand and comprehend the cycle.
