Viewing Cells

Light microscopes possess low magnification and resolution, but can view living specimens in their natural colours

  • Eukaryotic cells will be significantly larger than prokaryotic cells – however, without staining, only nuclei and chloroplast will likely be discernible

Electron microscopes possess higher magnification and resolution, but can only view dead specimens in monochrome (false colour can be applied)

  • Surfaces can be rendered via scanning electron microscopes, while cross-sections can be obtained via transmission electron microscopes
