1. An ordered set of events, culminating in cell growth and division into two daughter cells. 1

2.  What are cells made of? What are the functions of cell division? What happens during the cell cycle? 2

3. 3

4.  Cell division allows organisms to  Grow  Repair  reproduce 4

5. 5

6.  The formation of cells takes energy!  The time needed by the new cells to replenish their energy causes a "gap".  After cell energy reserves are restored, the cells begin to grow.  This is the longest phase of the cell cycle. 6

8. 8

9.  Synthesis means to make.  After a period of growth, each cell's original DNA is duplicated in the process of replication. 9

10.  The replication of DNA also takes a lot of energy!  The time taken by a cell to build up its energy reserves produces a second "gap". 10

11.  The process by which the DNA is divided into two identical sets before the cell divides.  Prophase  Metaphase  Anaphase  Telophase  Cytokinesis 11

17. Fibers move the chromosomes to the equator (middle) of the cell. 17

18. 18

19. The centromere of each pair of chromatids divides, separate and are pushed to opposite poles (apart) of the cell by the spindle fibers. 19

20. 20

21. All spindle fibers disappear, chromatids unwind and stretch as a nuclear membrane forms around each mass of chromatin. 21

22. 22

23.  Cytokinesis is the division of the cytoplasm of a parent cell.  The cell pinches together roughly in the center. 23

30.  Cancer is a disease of the cell cycle. Some of the body’s cells divide uncontrollably and tumors form. 30
