Unit 3: How Do Cells Reproduce?
Section A: Cell Cycle Background
 What factors limit cell size? Provide at least two limits.
 What is the Cell Cycle? Name the five parts.
 What is the purpose of interphase? 3 parts of interphase?
 What is the purpose of Mitosis? Cytokinesis?
 What is the end product of the cell cycle?
Section B: Genetic Material
 What is DNA?
 What is a chromosome? Chromatid? Chromatin?
 How many chromosomes are present in the human body?
 During what stage of the cell cycle are chromosomes copied?
 Why are telomeres important?
 How is a chromosome related to a chromatid?
 How is a chromosome related to chromatin?
 What is a histone? What is the purpose of a histone?
Include a diagram of a chromosome. Label a chromatid, centromere,
telomere, the long arm and the short arm (Not all in the textbook)
Section C: Mitosis and cytokinesis
 What are the two parts of the mitotic phase?
 What is the end result of mitosis?
 State and describe the stages of mitosis.
 How does cytokinesis in an animal cell compare to cytokinesis
in a plant cell?
Include a diagram showing the stages of mitosis and cytokinesis in an
animal cell. (Do use a picture of the cell cycle)
Include a diagram of cytokinesis in a plant cell (not in the textbook)
Section D: Cell Cycle Regulation
 What is an internal factor? What is an external factor?
 What is a growth factor? What would happen to an organism if
its growth factors were not working properly?
 What are checkpoints and what do they do?
 What are kinases and how are they activated? What is a cyclin?
 What is apoptosis?
 What can occur if the cell cycle is not properly regulated?
Section E: Cancer
 What is cancer? How is it caused?
 Why is cancer harmful?
 What is a carcinogen?
 Define benign, malignant and metastatic in relation to a tumor.
 Describe two different treatments for cancer.
Section F: Asexual Reproduction
 What is asexual reproduction?
 What is the name of the process where prokaryotes reproduce?
Describe what occurs in each step of this process.
 What are the advantages and disadvantages of asexual
reproduction?
Include a diagram of binary fission
