There are a few things that differ between a prokaryotic cell and a eukaryotic cell. One of the main obvious differences is that eukaryotes are a lot bigger than prokaryotes. Eukaryotes also have a lot more organelles than prokaryotes. If she can zoom in far enough to look at the DNA, the DNA in prokaryotes is circular and the DNA in eukaryotes, depending on which phase of cell division it is in, will either be in the form of chromosomes or in a big jumble, but isn't even able to be seen through the microscope.
