Mitosis is the process by which cells reproduce from one parent cell into two identical daughter cells.  It is divided into 4 phases: Prophase, metaphase, anaphase, and telophase. 

In Prophase, the chromosomes condense into visible threads that grow thicker and shorter.  The Chromosomes duplicate into sister chromatids, connected by a structure called the centromere.  Centrioles become visible, and move to opposite ends of the cell, remaining connected to each other through a mechanism called spindles. 

In metaphase the centromeres attach to the center of the spindle. 

In anaphase the sister chromatids separate becoming identical chromosomes, and the spindles pull the chromosomes to the opposite ends of the cell. 

In telophase, the cell splits at the equator, and the chromosomes uncoil and become invisible.  Each daughter cell is an exact clone of the original cell.

Mitosis is a type of cellular reproduction. Unlike meiosis, mitosis is asexual (only one parent's DNA is needed). Because there is only one set of DNA, there is no new genetic variety. The end results in two daughter cells identical to their parent cell. 

Mitosis is used as a way to grow for multicellular organisms such as ourselves. Mitosis can also be used to reproduce for unicellular organisms. Bacteria use mitosis to create duplications of themselves. 

The acronym, IPMAT, is used for the various steps of mitosis: interphase, prophase, (pro)metaphase, anaphase, and telophase. After IPMAT, cytokinesis (spliting of the cytoplasm) occurs.
