Question 2 • JPS-2026/27-WRHS-Environmental Science A-(CR-S1)-Miller

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?

Answer
A
transmission electron microscope
B
scanning electron microscope
C
compound light microscope
D
dissecting microscope

Explanation

A compound light microscope is best for observing microorganisms in pond water because it can be used to view living specimens and watch how they move. It also provides enough magnification to study and draw their structures. Electron microscopes require specimens to be prepared in ways that prevent observing their natural movement, while a dissecting microscope has too little magnification for most microorganisms.
