“Virtual Cell” Activity Go to www.virtualcell.com, then CLICK on “The Virtual Textbook”, then CLICK on “Cell Biology” to begin. The virtual cell will allow you to get a close-up view of several organelles in 3-D! You will be able to choose certain organelles within the cell and manipulate them by zooming in on the organelle, rotating the image, and dissecting several organelles to view their contents. Click on “Next Page” to move to the next page and answer each of the following questions. After viewing and studying an animation, place a CHECK in the corresponding space. CELL MEMBRANE 1. Click NEXT PAGE twice. Then, DRAW, COLOR, and LABEL a cross section of the cell membrane: 2. DRAW, COLOR, and LABEL a phospholipid: (INCLUDE the label of which end is hydrophobic and which end is hydrophilic) 3. LIST the 3 categories of protein found in a cell membrane and their purpose: a. ___________: _________________________________________________________ b. ___________: _________________________________________________________ c. ___________: _________________________________________________________ 4. Do all cell membranes contain cholesterol? Yes or No 5. What is the PURPOSE of the cholesterol? __________________________________________________ ____________________________________________________________________________________ ____________________________________________________________________________________ 6. VIEW an animation of a carrier protein: 7. VIEW an animation of channel proteins: 8. DEFINE diffusion: __________________________________________________________________ _________________________________________________________________________________ 9. View an animation of symports: 10. What is the glucose “hitching” a ride with? __________________________________________ 11. VIEW an animation of proteins using ATP’s: 12. GIVE an EXAMPLE of a protein using an ATP: _____________________________________________ 13. Which PROTEINS function in ORGAN REJECTION? ____________________________________________ 14. VIEW an animation for receptor proteins: 15. WHAT is binding to the receptor? ________________________________________________________ 16. VIEW an animation of endocytosis: 17. DEFINE endocytosis: __________________________________________________________________ ____________________________________________________________________________________ 18. ______________________ is engulfing ________________________. 19. The OPPOSITE of endocytosis is ________________________. 20. VIEW animation: NUCLEUS 21. GIVE the FUNCTION of the nucleus: ____________________________________________________ 22. Inside the nucleus you will find ________________________ and ___________________________. 23. What is the FUNCTION of the chromatin? ________________________________________________ 24. What does the nucleolus do? ________________________________________________________ CYTOPLASM 25. WHERE is the cytoplasm located? ________________________________________________________ ENDOPLASMIC RETICULUM 26. The E.R. is found in which TWO forms? _______________________ and _______________________ 27. What is the DIFFERENCE between the two? _________________________________________________ RIBOSOMES 28. What is the FUNCTION of ribosomes? ______________________________________ GOLGI APPARATUS (GOLGI BODIES) 29. What is the FUNCTION of the golgi apparatus? ______________________________________________ LYSOSOMES 30. Lysosomes are also called ________________________________________________________. 31. Lysosomes contain _____________________________________________________________. MITOCHONDRIAN 32. This is the site of _______________________________________________________________. CHLOROPLASTS 33. These are ONLY FOUND in ________________________________________________________. 34. The FUNCTION is ________________________________________________________________. CENTRIOLES 35. Centrioles are FOUND ONLY in _____________________________________________________. 36. Centrioles FUNCTION in __________________________________________________________. VACUOLES 37.
