1. Draw a few cells of Gloeocapsa (no more than eight). Label the gelatinous sheath. Using your
measurements of the diameters of the field of view (FOV; see last week’s lab), estimate the size of a
Gloeocapsa cell.




                                                                 Total magnification: ________

                                                                 Approx. cell size: __________




2. Would you expect to see nuclei in Gloeocapsa? Why or why not?




3. On average, how many cells of Gloeocapsa are contained within one sheath? ___________________


4. Draw a few cells found in the yogurt. Estimate their size.




                                                                Total magnification: ________

                                                                Approx. cell size: __________




5. Which type of bacteria was more abundant in your yogurt?        ________________________________




                                                                                                        1

6. Draw a Paramecium and estimate its size.




                                                               Total magnification: ________

                                                               Approx. cell size: __________




7. What structures does Paramecium use for movement?               ________________________________


8. Draw a few of the Elodea cells. Estimate the size of an Elodea cell.




                                                              Total magnification: ________

                                                              Approx. cell size: __________




9. Draw the best view of the onion cells. Estimate the length of an onion cell.




                                                            Total magnification: ________

                                                            Cell length: __________



10. Do onion                                          cells have chloroplasts? Explain.




                                                                                                  2

11. Draw the best view of the cheek cells. Estimate the size of one cheek cell.




                                                          Total magnification: ________

                                                          Approx. cell size: __________




12. Can you see organelles in the stained preparation of the cheek cells that were not visible in the
unstained? Can you make an educated guess at to what the newly visible structures are?




                               Prokaryote or eukaryote?            Kingdom                Average cell size
