____________________________ Name Hour Biology Review Guide Ch. 5 Cell Cycle + Mitosis Words to know: Cell Cycle Mitosis Cytokinesis Chromosome Histone Chromatin Chromatid Centromere Telomere Prophase Metaphase Anaphase Telophase Apoptosis Cancer Benign Malignant Stem Cell Asexual reproduction Tissue Organ system Organ Cell differentiation Essential Questions/Topics 1. The cell cycle has four main stages--G1, S, G2, and M. What occurs in the cell during each stage? Draw and label the Cell Cycle. (Fig. 1.1) 2. Compare the rates of cell division occurring in your neurons and your hair follicles. Explain why there is such a difference. 3. What is the relationship between a cell’s surface area and its volume? 4. Describe the structure of a chromosome. How do proteins help it condense? Draw and label a fully condensed chromosome. (Fig 2.2) 5. Describe what happens in each main phase of mitosis--prophase, metaphase, anaphase and telophase. (Fig 2.4) How does cytokinesis differ between plant and animal cells? 6. What is cyclin? How is it suppose to work? What happens when it doesn’t work correctly? 7. List 3 characteristics of stem cells.
