A scientist wants to magnify a pollen grain 8,000 times and examine the ridges and pores on its surface.Which one of the following instruments would be best?

Question

Quizplus · Accepted Answer

A scanning electron microscope (SEM) is best for examining the ridges and pores on the surface of a pollen grain at a high magnification of 8,000 times. SEM uses a beam of electrons to scan the surface of a sample and create high-resolution three-dimensional images, providing detailed information on the surface structure of the sample. In contrast, a fluorescence confocal microscope would be useful for examining the internal structures of cells and tissues, while a transmission electron microscope is more suited for examining the ultrastructure of cells and subcellular organelles. An inverted light microscope is not capable of magnifying a sample to 8,000 times magnification.
