Cell Growth and Division
Chapter 5
A. Section 5.1
1. Where do you think G0 would fit into the cell cycle diagram? Sketch and label the
phases of the cell cycle (p.130) diagram and include G0.
2. During which stage of the cell cycle is the DNA copied?
3. What is the name of the stage in which the nucleus divides?
4. What is the name of the stage in which the cytoplasm divides?
5. What would a cell look like if you treated cells with a chemical to block cytokinesis?
(What would a cell look like right after mitosis, before cytokinesis?)
6. Which stages of the cell cycle generally require about the same amount of time in all
human cells?
7. What limits the maximum size of a cell? Describe why it is better for a cell to have a
larger surface area to volume ratio?
Activity #1: CELL CYCLE FOLDABLE
B. Section 5.2
1. Draw what a chromosome looks like during metaphase. Label the chromatids and
centromere. Using your online textbook, complete the mitosis matching activity p.136
2. List and describe the stages of the division of the nucleus (mitosis).
3. Why are daughter cells genetically identical to each other and to the original cell?
4. How do prophase and telophase differ?
Activity #2: HOW ONE CELL BECOMES TWO – Mitosis
C. Section 5.3
1. What is the difference between and internal regulation factor and external factor?
p.140
2. What is the job of a growth factor and give an example.
3. List and describe the job of two important internal factors p.141
4. What is apoptosis and describe its role during human embryonic development.
5. How do cancer cells differ from healthy cells?
6. Describe the difference between a malignant tumor vs a benign tumor.
7. Why are malignant tumors harmful?
8. What is a carcinogen and give examples.
D. Section 5.4
1. How does mitosis differ from binary fission?
2. Describe a disadvantage of asexual reproduction.
3. Briefly explain why cutting a flatworm into pieces would not kill it.
4. How does and organism benefit from reproducing asexually and sexually?
E. Section 5.5
1. How does communication between cells help maintain homeostasis?
2. Why is cell differentiation an important part of the development of a multicellular
organism?
3. What are stem cells?
4. What is the difference between adult stem cells and embryonic stem cells?
5. How are cells, tissues, organs and organ systems related? Give an example.
6. What role does the location of a cell play in cell differentiation?
