1. A student was asked to use the scale bar shown to calculate the magnification of a
cell on a photomicrograph.
2 μm
Which method could the student use to calculate the magnification of the cell?
A. divide the diameter of the cell by the length of the scale bar, both measured in the same units of
length
B. B measure the diameter of the cell in millimetres, multiply by 2000 and divide by the length of
the scale bar measured in millimetres
C. C measure the length of the scale bar in millimetres, convert to micrometres and divide by 2
D. D measure the length of the scale bar in millimetres,
