Electron Microscopy
Electron microscopes have revolutionized our understanding of cell structure by providing much higher resolution than light microscopes.
Why can't we see ribosomes with a light microscope?
What is Electron Microscopy?
"An electron microscope is a high-powered microscope that uses electron beams to achieve resolutions much higher than possible with light."
Which term correctly completes this GCSE Biology equation or calculation statement? A ____ is the total of results ÷ number of results
Which term correctly completes this GCSE Biology equation or calculation statement? ____ change = (final − initial) ÷ initial × 100
Which option correctly completes the statement? In photosynthesis practicals, moving a lamp ____ increases light intensity
Which answer best completes the statement? Control variables are kept the same for a ____ test
Power of Electrons
Electron microscopes use a beam of electrons instead of light.
They have a much higher resolution (around 0.2nm) and higher magnification.
They allow us to see sub-cellular structures like mitochondria and chloroplasts in detail.
Specimens for electron microscopy must be dead because the process happens in a vacuum.
