Cell A has entered early interphase. This when te cell carries ot all of the normal life functions of the cell. Cell B is beginning to make the chromosomes into short and thick rods. This indicates the first stages on mitosis or cell division.

The larger cell has fully entered into prophase, where the chromosomes have become thicker and shorter in size. This is when they begin to move towards the middle of the cell.

The C cell has reached the middle of mitosis, which is called metaphose. During Metaphose the chromosomes have been developed into short and thick rods, which move to the centre of the cell into a line.

In this stage the cell D has entered into early anaphase where each chromosome has doubled and the two parts are seperating as they move away from eachother the form into a V shape facing eachother. S is indicating the lower level of the cell where the spindle fibers are fait but can be seen.

In cell E all the chromosomes have now completely seperated, this indicates that the cell has reached te main part of mitosis. This is when the cell produces two duplicated sets of chromosomes. The two new sets of chromosomes are beginning to move further away from each other. The B cells are going into the first stages of prophase.

In cell F two sets of chromosomes are now much further apart now. This is the stage of late Anaphase. Once the two sets get the farthest apart from eachother they willl start to organize themselves into two seperate nucleus. Although the two cells have starting making themselves into nucleus no cell wall has developed yet. 

The is Telophase, the final stage of Mitosis.  Two sets of chromosomes in Cell G have now began to form a dense mass which will become two different nuclues for each new cell. Single chromosomes can no longer be seen. In between the two cells are spindle fiber, where you can see a faint line where the new cell wall will begin to form between the two new cells.

The Cell H shows the very last stage of Mitosis. The cell walls still haven't been fully built between the two cells. The Cell A have finished mitosis, and have moved into interphase. The new nuclui can be seen, and the cell walls have been completely built, which divides the original cell into two completely different cells. The two cells will soon grow in size, and after a point of time they will then begin mitosis again.
