Visit this website and read the introductions and follow all directions: http://learn.genetics.utah.edu/content/variation/reproduction/
Write any interesting information about the organism’s reproduction. Place a check on asexual (one parent), sexual (two parents), or both based on your quiz answers on the website (green means correct, red is incorrect). Be prepared to share information that you learned in class.
Organism Interesting Information Asexual Reproduction
2. How many chromosomes are there in somatic (non-sex, or non-gamete) human cells?
3. Draw a sketch that shows how mitosis in plant cells is different than mitosis in animal cells (in
particular, be sure to focus on how the cytoplasm divides into two daughter cells).
4. DNA is located in structures called: a. centrosomes b. centromeres c. centrioles d. chromosomes
5. During the early stages of mitosis, sister chromatids are held together by a tiny structure called the: a. centriole b. centromere c. centrosome d. nucleus
6. When an elephant cell, which contains 56 chromosomes, reproduces by mitosis, each daughter cell
contains ____ chromosomes: a. 28 b. 56 c. 84 d. 112
7. Centrioles are not present during mitosis in what kind of cells? a. plant b. animal
8. Below is a diagram of the cell cycle, but some stages are missing. Fill in the missing stages using the
following: G1 phase S phase G2 phase Metaphase Telophase
9. In which stage is DNA replicated?
10. In which stage is the cell NOT preparing or participating in cell division?
10
11. Label each of the following statements as being descriptive of interphase, prophase, metaphase,
anaphase, or telophase:
a. _____ chromosomes are not yet visible
b. _____ sister chromatids have just broken away from each other at the centromere
c. _____ nuclear membrane is reforming
d. _____ sister chromatids are still attached to each other at the centromere, but chromosomes
haven’t lined up yet
e. _____ nuclear membrane is breaking down
f. _____ chromosomes have lined up in a “single file” line
g. _____ the stage that includes cytokinesis
h. _____ organelle replication and protein synthesis occurs
i. _____ in terms of changes in the nuclear membrane, this stage is the opposite of prophase
12. Observe the cell shown below (it has just finished cytokinesis)
a. Diagram how this cell would appear if it were seen in each of the following stages. Be sure that
each diagram shows the shape of the cell, whether or not the nucleus is visible, and the
chromosomal arrangement of the cell.
b. Then, label using sister chromatids, centriole, spindle, and centromere.
centrioles
nuclear membrane
nucleus
cell membrane
a. prophase of mitosis b. anaphase of mitosis
11
13. When do cells need to go through mitosis? (NOT all the time)
14. Look at the following pictures and label each one with the appropriate stage of mitosis.
a. b. c.
15. In the picture below (from a light microscope) of dividing cells near the tip of an onion root, I have
indicated 5 cells. Identify which cell is in each of the following phases: interphase, prophase,
metaphase, anaphase, and telophase. Give one piece of evidence for each label (in other words –
explain why you think that cell is in that phase).
