1What protein regulates the

cell cycle?

Cyclin

2In which phase of mitosis are

the chromosomes split in half?

Anaphase

3Name the 5 phases of the M-phase!

Prophase, Metaphase, Anaphase, Telephase, and Cytokenisis

4Define apoptosis and give an

example.

Programmed cell death (such as the space between your toes)

5Two chromotids are connected

in the middle by the __________.Centromere

6If a cell enters Interphase with

6 chromatids – how many chromatids will it have during metaphase?

12 chromatids

7During the cell cycle how do you know if its an animal cell or a plant cell?

Plant cell forms a cell plate during cytokinesis

8When do chromosomes first appear in the cell cycle?

Prophase

9What is an advantage of

asexual reproduction?

Rapid growth

10What is the function of the

centriole?

Organize the Spindle fibers

11During which stage of mitosis

do the spindle fibers attach to the centromere?

Metaphase

12Programmed Cell death is called ________.

Apoptosis

13In eukaryotic cells, what do cyclins do?

Regulate the timing of the cell cycle.

14Embryonic stem cells are

found in _____________ cells.PluripotentMultipotentTotipotentSimplepotent

Pluripotent

15

Why does cancer happen?

Cells have lost their ability to to control cell growth.

16

In normal cells what causes cells to stop dividing?

Growth factors or external regulators (when they are surrounded by other cells)

17

Mitosis and Cytokinesis are the only phases of the ____________.

M-phase

18

Stem cell research is controversial when cells from the _______________ are used.

Embryonic or pluripotent cells

19

What causes cancer cells to metastasize?

Move into the blood stream and spread.

20

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

6:1

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.

22

When is demand on the DNA too great to function properly?

When surface area to volume ratio is too small.

23

In which phase does the cell experience the most growth?

G1

24

In prokaryote cells, how are cells replicated?

From 1 parent cell dividing into 2 identical cells

25

What is the shortest phase of mitosis?

Metaphase
