1 Tic Tac Toe

2 1  What protein regulates the cell cycle? Cyclin

3 2  In which phase of mitosis are the chromosomes split in half? Anaphase

4 3  Name the 5 phases of the M-phase! Prophase, Metaphase, Anaphase, Telephase, and Cytokenisis

5 4  Define apoptosis and give an example. Programmed cell death (such as the space between your toes)

6 5  Two chromotids are connected in the middle by the __________. Centromere

7 6  If a cell enters Interphase with 6 chromatids – how many chromatids will it have during metaphase?– 12 chromatids

8 7 During the cell cycle how do you know if its an animal cell or a plant cell? Plant cell forms a cell plate during cytokinesis

9 8 When do chromosomes first appear in the cell cycle? Prophase

10 9  What is an advantage of asexual reproduction? Rapid growth

11 10  What is the function of the centriole? Organize the Spindle fibers

12 11  During which stage of mitosis do the spindle fibers attach to the centromere? Metaphase

13 12  Programmed Cell death is called ________. Apoptosis

14 13 In eukaryotic cells, what do cyclins do? Regulate the timing of the cell cycle.

15 14  Embryonic stem cells are found in _____________ cells.  Pluripotent Pluripotent  Multipotent Multipotent  Totipotent Totipotent  Simplepotent Simplepotent Pluripotent

16 15  Why does cancer happen? Cells have lost their ability to to control cell growth.

17 16  In normal cells what causes cells to stop dividing? Growth factors or external regulators (when they are surrounded by other cells)

18 17 Mitosis and Cytokinesis are the only phases of the ____________. M-phase

19 18 Stem cell research is controversial when cells from the _______________ are used. Embryonic or pluripotent cells

20 19 What causes cancer cells to metastasize? Move into the blood stream and spread.

21 20 What ratio of surface area to volume is best for cells? 6:1, 3:1, or 2:1? 6:1

22 21 If the volume of the cell is too large, what will happen to it’s waste? The waste will be too large to find ways out of the cell – waste will build up.

23 22 When is demand on the DNA too great to function properly? When surface area to volume ratio is too small.

24 23 In which phase does the cell experience the most growth? G1G1

25 24 In prokaryote cells, how are cells replicated? From 1 parent cell dividing into 2 identical cells

26 25 What is the shortest phase of mitosis? Metaphase
