Name__________________ Date___________________ Block__________________ CELL BIOLOGY STUDY GUIDE- Quest #1 *Review all readings, homework, class work, and journal notes. *You will need to know the function of all cell structures. 1. How are the cells of unicellular organisms different than the cells of multicellular organisms? __________________________________________________________________ __________________________________________________________________ _______________________________________________________________ 2. When Robert Hooke saw “juice” in some cells, what structure was he really looking at? __________________________________________________________________ ________________________________________________________________ 3. What are two structures found only in plant cells? (Do not include vacuoles— animal cells can have small vacuoles.) __________________________________________________________________ ________________________________________________________________ QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. http://www.biologycorner.com/worksheets/ QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. 4. Every cell needs a membrane. Why? __________________________________________________________________ __________________________________________________________________ _______________________________________________________________ 5. What are the three parts of the Cell Theory? __________________________________________________________________ __________________________________________________________________ _______________________________________________________________ 6. Please describe the structure of a phospholipid bilayer. What kind of molecules is it made up of? How are the molecules oriented? Draw a picture to help explain this. __________________________________________________________________ __________________________________________________________________ _______________________________________________________________ _________________________________________________________________ 7. How do the following structures work together? Think about the “Cell Factory.” Ribosome Endoplasmic Reticulum Golgi complex __________________________________________________________________ __________________________________________________________________ _______________________________________________________________ _________________________________________________________________ 8. How do mitochondria and chloroplasts work together to help a plant cell work? __________________________________________________________________ __________________________________________________________________ _______________________________________________________________ _________________________________________________________________ 9. Explain how the nucleus can control what happens in a lysosome. __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ 10. Define diffusion: __________________________________________________________________ __________________________________________________________________ _______________________________________________________________ 11. A bottle of perfume is spilled in the hallway near the humanities room. Eventually, the smell reaches the science room. What is happening in terms of diffusion? __________________________________________________________________ __________________________________________________________________ _______________________________________________________________ 12. What would happen to a grape if you placed it in corn syrup? Would it swell, shrink, or stay the same? Please explain what happens in terms of osmosis. __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ ______________________________________________________________ 13. The cell cycle describes a cell’s life cycle. It begins when the cell is formed and ends when the cell divides and form new cells. What needs to happen before a cell divides? (Think about what happens during Interphase.) _________________________________________________________________ __________________________________________________________________ ________________________________________________________________ 14. Please describe important events during each phase of mitosis. Feel free to use drawings to help you. a. Prophase:____________________________________________________ ____________________________________________________________ _________________________________________________________ b. Metaphase:__________________________________________________ ____________________________________________________________ __________________________________________________________ c. Anaphase:___________________________________________________ ____________________________________________________________ __________________________________________________________ d. Telophase:___________________________________________________ ____________________________________________________________ _________________________________________________________
