Microslide Activity: Animal Mitosis
1. What is a zygote?
2. How many masses of chromatin can be seen in the cell? Where did the masses come
from?
3. T or F. The chromatin contributed by the sperm and egg are equal in amount.
4. How many chromosomes where supplied by each parent to form the zygote?
5. During pro-metaphase, what happens to the chromosomes after fertilization?
6. What is the letter “P” pointing to in slide 3 (metaphase stage)? Why are two letters
labeled “E” located at the top and bottom of each cell?
7. Where are centromeres located? What is the purpose of the centromere?
8. How is slide 4 different from slide 3?
9. Describe what occurs during early anaphase.
10. How many chromosomes are present in anaphase?
11. What are the spindle fibers doing to the chromosomes during anaphase?
12. Why do chromosomes look beaded in some places?
13. How does the shape of the cell look different in slide 7 compared to previous slides?
Why does it look this way?
14. How many daughter cells are formed after mitosis? How many chromosomes do
each of these cells have?
15. How is mitosis in a human different from mitosis in an ascaris?
16. Compare the microslides to the pictures in your textbook. Determine which stage
from your textbook is presented in each slide. (Hint: some of the slides show the
same stage.)
