Organisms, cells, and structures of varying sizes have been provided for your observation. Draw each using
a magnification that makes sense (i.e. close enough that you can see one representative cell clearly but not so
close that the single cell doesn’t all fit in the field). Indicate the total magnification, field diameter at this
magnification, and size of the object you are observing (use the field diameter to guesstimate). Cell sizes are
to be reported in micrometers (µm) and 1 millimeter is equal to 1000 micrometers.
