Question
Electron microscopes are essential for examining structures of what size range or type that cannot be resolved with light microscopes?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Page 11 notes that electron microscopes 'examine structures too small to be resolved with light microscopes such as viruses or objects or molecules having sizes smaller than 0.2 µm'.
Hint
Think about the smallest entities that require powerful magnification beyond what visible light can offer.
