Show transcript
Most cells are too small to be seen without a microscope.
Comparison of the sizes of cells and cell structures.
Light microscopes have limited magnification and resolution.
Electron microscopes have greater magnification and resolution, allowing much smaller structures to be seen clearly.
Electron microscopy has increased our understanding of sub-cellular structures.
