Cell Division
By Cindy Grigg
  

1     Living things grow by cell division. Cell division also replaces dead or worn-out cells. Cells divide to multiply. The process that cells go through when they divide is called mitosis. During mitosis, a single cell splits into two cells. The nucleus of the cell divides first. This is called mitosis. Then the cytoplasm divides. This is called cytokinesis.
 
2     The two cells produced by mitosis are called daughter cells. They are identical. Mitosis causes the number of cells to double. At the end of the process, there are twice as many cells. For example, if three cells go through mitosis, six cells are produced. If those six cells go through another cell division, twelve cells are produced.
