Cell Division Study Guide
1. Which process is represented in the diagram below?
2. If the chromosome number in an egg cell nucleus of a corn plant is 10, then what is the normal chromosome number in a a root epidermal cell of the same corn plant?
3. Which is the correct sequence for the stages of mitotic cell division represented by the diagrams below?
A B C D
Telophase Prophase Anaphase Metaphase
4. What stage of mitotic cell division is below? What does A indicate? What does B indicate?
5. What is the advantage of sexual reproduction for a species? What type of cell division is this?
6. Label the images below as sexual or asexual, and identify the process.
7. What is uncontrollable cell division called?
8. In the diagram below, which is Phase I and Phase II of meiosis?
9. Identify and describe the image below.
10. In the diagram below, describe the percent of cells that are dividing (in any stage of mitosis).
22 interphase and 8 in mitosis(dividing):
22/30 =73% not dividing and 8/30 = 27% dividing(mitosis)
11. What is a zygote and from what cell division does it result?
12. Is a zygote haploid or diploid? Gamete?
13. Identify each type of cell division
Mitosis (diploid to diploid) Meiosis (diploid to haploid)
14. Identify and describe each stage of mitosis in the figures below and sequence (put them in order) them.
15. If 78 chromosomes exist in somatic cells of a dog, then how many chromosomes exist in gametes? How do you figure this out?
16. Which of the following is not a somatic cell?
Skin, liver, nerve, sperm, stomach
17. Why is it necessary for meiosis?
18. If the number of chromosomes in an egg cell of a pig is 19, then how many chromosomes are in a pig’s stomach cells?
19. What are the purposes of mitosis?
Growth, repairing cells
20. What are the purposes of meiosis?
Make gamete/sex cells
Leads to genetic variation (allows for adaptations in changing environment)
