Name: _______________________________________ Period: __________ Date: __________ Chapter 10 Study Guide Lesson 10.1 – Cell Growth, Division, & Reproduction Know VOCABULARY: Cell division Asexual reproduction Sexual Reproduction Know CONCEPTS: What are some of the difficulties a cell faces as it increases in size? 1. ______________________________________________________________________________ ______________________________________________________________________________ 2. ______________________________________________________________________________ ______________________________________________________________________________ As a cell’s size increases, what happens to the ratio of its surface area to volume, and why is this ratio important? What does a cell do before it divides and why? Remember: Cell division results in an increase in the ratio of surface area to volume for each daughter cell. This allows for the efficient exchange of materials within a cell. What is asexual reproduction? ____________________________________________________________ Their offspring inherit _________________________ genetic information from the parent cell. Advantages: ____________________________________________________________________ Disadvantages: __________________________________________________________________ What is sexual reproduction? _____________________________________________________________ Their offspring inherit _________________________ genetic information from the parent cells. Advantages: ____________________________________________________________________ Disadvantages: __________________________________________________________________ What is an advantage of being able to reproduce both asexually AND sexually? Lesson 10.2 – The Process of Cell Division Know VOCABULARY: Chromosome Chromatin Cell cycle Interphase Mitosis Cytokinesis Prophase Centromere Chromatid Centriole Know CONCEPTS What role do chromosomes play in cell division? Describe prokaryote chromosomes and eukaryote chromosomes: How many chromosomes do humans have? What are the main events of the cell cycle? What events occur during each of the four stages of mitosis? How do daughter cells split apart after mitosis? What is the term for it? Metaphase Anaphase Telophase Lesson 10.3 – Regulating the Cell Cycle Know VOCABULARY: Cyclin Growth Factor Apoptosis Cancer Tumor Know CONCEPTS: What is the cell cycle controlled by? What happens when cells do not respond to the signals that regulate cell growth? What is the name of the protein that they discovered that regulates the cell cycle? What are Internal Regulators and how do they contribute to the cell cycle? What are external regulators and how do they contribute to the cell cycle? What is the name of the process of programmed cell death? What is cancer and how do cancer cells differ from other cells? What are tumors? What is the difference between benign and malignant tumors? What are some factors that cause cancer? What treatments are available?
