• The cell will immediately divide.

• Cell processes will continue unchanged.

• The cell will eliminate wastes more efficiently.

• Many chemical reactions in the cell will slow down or even stop.

9. Eukaryotic cells undergo mitosis as part of the cell cycle. What does a cell produce as a result of mitosis?
