To study cells with a light microscope, different types of stains are usually available. Why is it generally more useful to stain eukaryotic cells than prokaryotic cells?
Prokaryotic cells are simpler so the stain more easily diffuses throughout the cell.
Prokaryotic cells are more complex, so there are more compounds and surfaces for the different stains to attach to and, thereby, provide visual detail about.
Eukaryotic cells are simpler so the stain more easily diffuses throughout the cell.
