Bacterial cells, which in general have dimensions lying between 1-4 um, are resolved only with difficulty under the light microscope. At magnifications of 400 times natural size, large bacteria stained in methyl violet can just be seen as small, dark specks. Providing the resolution of the light microscope is good, higher magnifications (e.g., 1000x or 1500x) do reveal a little more of the internal structure of bacterial cells. The light photomicrograph (see image below) shows a single type of bacterial cell treated with Giemsa stain. Measure the length of cell X, and assuming the actual length to be 3 um, calculate the actual magnification. - Cell X 2 11 12 13 14 15 2 3 Centimeters Inches

Question
Answer these questions. 1. What is the actual magnification of Cell X? 2. How has magnification of this number of times been achieved if the light microscope itself (used in taking the photograph) only magnifies 1500 times?
