A
Light microscope.
B
Electron microscope.
C
Both light and electron microscopes.
D
None of the above, cells can be seen with the human eye.
Verified step by step guidance1
Understand the size range of prokaryotic cells, which typically range from 0.1 to 5 micrometers in diameter.
Recognize that light microscopes can magnify objects up to about 1000 times, which is sufficient to visualize prokaryotic cells.
Learn that electron microscopes provide much higher magnification and resolution, allowing for detailed visualization of cellular structures.
Consider the limitations of the human eye, which cannot resolve objects smaller than about 0.1 millimeters, making it impossible to see individual prokaryotic cells without magnification.
Conclude that both light and electron microscopes are suitable for visualizing prokaryotic cells, each offering different levels of detail and magnification.
