Multiple Choice

A researcher wants to film the movement of chromosomes during cell division. Which type of microscope should she choose, and why is it the best choice?

Light microscope because of its high resolving power

Transmission electron microscope because of its high magnifying power

Scanning electron microscope because of its ability to visualize the surface of subcellular objects

Transmission electron microscope because of its high resolving power

Light microscope because the specimen is alive

Verified step by step guidance

Understand the requirements of the research: The researcher wants to film the movement of chromosomes during cell division, which implies observing live cells.

Consider the characteristics of different types of microscopes: Light microscopes, transmission electron microscopes, and scanning electron microscopes each have unique features.

Evaluate the suitability of each microscope: Transmission electron microscopes and scanning electron microscopes require specimens to be fixed and dead, which is not suitable for observing live cell processes.

Recognize the advantage of light microscopes: Light microscopes allow for the observation of live specimens, making them ideal for filming dynamic processes like chromosome movement during cell division.

Conclude the best choice: Given the need to observe live cells, the light microscope is the best choice due to its ability to visualize living specimens without compromising their viability.
