A scientist wants to magnify a pollen grain 8,000 times and examine the ridges and pores on its surface. Which of the following instruments would be best?
A) a transmission electron microscope
B) a scanning electron microscope
C) a fluorescence microscope
D) a light microscope

Question

Quizplus · Accepted Answer

A scanning electron microscope (SEM) is the best choice as it uses electrons to create a high-resolution 3D image of the surface of the specimen, allowing for the examination of the ridges and pores on the pollen grain with a magnification of up to 500,000 times. The transmission electron microscope (TEM) is used to examine the internal structure of specimens, while the fluorescence microscope is used to visualize specific molecules or structures within cells. The light microscope has a limited resolution and cannot magnify up to 8,000 times.
