Question

What is the primary limitation of a Bright-field microscope when observing living cells?

Correct Answer
D It can only be used with stained, nonviable specimens.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The text states, 'Limitation: Absence of contrast between the specimen and the surrounding medium, which makes it difficult to observe living cells.' This is the key challenge for bright-field microscopy with live, unstained samples.

Think about what makes it hard to see a transparent object against a similar background.
