1. The stage of the cell cycle following G 2 MITOSIS

2. In order for the nucleus to divide, the cell must follow some very special steps:  P prophase  M metaphase  A anaphase  T telophase THE PURPOSE OF MITOSIS IS TO DIVIDE THE CELL’S NUCLEUS

3.  The nuclear membrane will disintegrate  The nucleolus disappears  Chromosomes condense  The spindle apparatus begins to form PROPHASE

4. The chromosomes attach to the spindle apparatus and align along the equator of the cell. METAPHASE

5. The microtubules shorten and pull sister chromatids to opposite poles of the cell ANAPHASE

6.  The chromosomes reach the poles of the cell  The nuclear membranes re-form  The nucleolus reappears  Chromosomes decondense TELOPHASE

7. The purpose of cytokinesis is to divide the cell (and it’s cytoplasm). Cytokinesis is not the same for plant and animal cells CYTOKINESIS FOLLOWS TELOPHASE

8.  In plant cells a CELL PLATE forms that divides the cells.  In animal cells, a cleavage furrow forms at the equator of a cell and pinches downward until the cell divides. CYTOKINESIS IS DIFFERENT IN A PLANT CELL COMPARED TO AN ANIMAL CELL.

9. WHAT CAN WE DO TO REMEMBER THOSE STEPS?

10. 1.During what stage of mitosis does the nuclear membrane begin to disappear? 2.During what stage of mitosis do the chromosomes line up at the cell’s equator? 3.What is/are the product(s) of mitosis? 4.What stage of mitosis do you see below? DID YOU GET IT?
