be genetically identical to each other.
b.
be genetically identical to the parent cell.

have half the genetic material found in the parent cell.

Which of the following statements regarding the differences between mitosis and meiosis is false?
a.
In mitosis four daughter cells are produced, whereas is meiosis two daughter cells are produced.
b.
Cells produced by mitosis are diploid, whereas cells produced by meiosis are haploid.
c.
In mitosis cytokinesis occurs once, whereas in meiosis cytokinesis occurs twice.

1.
Bella and Edward observed the above cell under their microscope. At which phase of mitosis should they identify this cell?
a.
prophase
b.
metaphase
c.

d.

2.
Draw the end products that will be formed if this cell undergoes mitosis. (2 points)
3.
Draw the end products that will be formed if this cell undergoes meiosis. (2 points)
4.
An oncologist (a physician that specializes in cancer) compares 2 biopsy (tissue) samples by looking at the percentage of cells in
mitosis. Sample #1 has 8% of cells in mitosis and Sample #2 has 19% of cells in mitosis. These samples are of the same tissue
type.
a.) Which sample is more likely to form a tumor? Explain why. (2 points)
Cancer begins when cells divide uncontrollably (even when you don’t need them). Sample 2 has more cells in mitosis,
which means more of the cells in the tissue are in the process of dividing.
b.) What is one thing to look for when trying to decide if the tumor is benign or malignant? (1 point)
Malignant tumors can invade nearby tissues or spread to other parts of the body through the blood stream. Benign
tumors cannot. Only malignant tumors are considered cancerous.
