Question

Scientists use different types of microscopes to observe objects that are not visible to the naked eye. A scientist is reviewing various samples of pond water to determine what species of microorganisms live in the pond. The scientist wishes to make drawings of the structure of each microorganism and study each one's method of movement. Which of the following microscopes would be best for the scientist to use?
a.
transmission electron microscope
b.
scanning electron microscope
c.
compound light microscope
d.
dissecting microscope



Please select the best answer from the choices provided


A
B
C
D

Answer 1

C

A compound light microscope is best because it can magnify microorganisms enough to see their structure and — importantly — view living specimens so the scientist can observe their methods of movement. Electron microscopes (A and B) require vacuum and kill samples, and a dissecting microscope (D) has too low magnification for most microorganisms.
