Cell Cycle
Mitosis
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
Binary Fission
____telophase__________1. When the spindle fibers disappear and the nuclear
membrane reforms.
_____interphase ________2. When the cell grows and duplicates the chromosomes.
_____anaphase__________3. When the sister chromatids separate
_____prophase__________4. When the spindle fibers form and the nuclear membrane
breaks down
______cytokinesis_______5. When the cleavage furrow appears
_______cytokinesis______6. When the cell plate is formed
________metaphase_____7. When the chromosomes align themselves on the equator of
the cell
___cell cycle___________8. The sequence of growth and division of a cell.
______mitosis__________9. The name for nuclear division.
____binary fission______10. Prokaryotic cell division.
11.
Name three reasons why multicellular organisms might need to add
cells by cell division:
a.DNA overload – too many demands on the DNA, it can’t make enough proteins to meet the needs of the cell
b. has difficulty exchanging materials
c. to increase the surface area to volume ratio
12. Why is it important that chromosomes be replicated?
Each new daughter cell will need a complete copy of the DNA
In the cells size and diffusion lab we determined the relationship between surface area to volume and surface
area to mass of a model cell:
If one side measures 0.001cm:
13. What is the area of one face of your cell? ______0.000001 cm2___(s2)___________
14. What is the total surface area of your cell? ______0.000006cm2__(6 x s2)________
15. What is the volume of your cell? ____0.000000001cm3 (s3)_____________
16. What is the SA:V ratio? __6000:1__________
17. Compared to the smallest cell in your lab that had a SA:V ratio of 6:1, how much faster is the diffusion of
this cell? ___it will happen 1000 times faster____________
18. Label all the parts of the cell cycle shown. What happens suring part B?
A = G1 B = S C = G2 D = M
DNA synthesis
19. Identify the phase of the cell cycle of each picture:
a.
b.
d.
prophase
telophase
anaphase
c.
e.
metaphase
interphase
