A student wants to watch living organisms under magnification. Which instrument suits this best?
AAn electron microscope
BA radio telescope
CAn X-ray machine
DA light microscope
Answer & Solution
Correct answer: D. A light microscope
1. Light microscopes pass visible light through lenses and are advantageous for viewing living organisms.
2. Preparing a specimen for an electron microscope kills it, so living cells cannot be viewed that way.
3. The electron microscope wins on magnification and detail, but not on keeping the specimen alive.
4. Telescopes and X-ray machines are not tools for magnifying cells at all.
