A student says that a light microscope used at a magnification of ×2000 \times 2000\,×2000 would show ribosomes clearly.
Which is the best evaluation of this statement?
Incorrect, because extra magnification without extra resolution gives a blurred image.
Incorrect, because ribosomes are only found in bacterial cells and not in plant cells.
Correct, because ribosomes are larger than the resolution limit of a light microscope.
Correct, because any structure can be seen if the magnification is made high enough.
