The lenses of a brightfield microscope are responsible for which of the following functions?

• A. Magnifying the image of the specimen
• B. Staining the specimen to increase contrast
• C. Regulating the temperature of the specimen
• D. Illuminating the specimen with ultraviolet light

Answer: (A)

Verified step by step guidance

1. Understand the primary components of a brightfield microscope, focusing on the lenses and their role in the imaging process.
2. Recall that the lenses in a brightfield microscope are designed to bend light rays to enlarge the image of the specimen, which is known as magnification.
3. Recognize that staining the specimen is a separate preparatory step done before viewing, not a function of the lenses themselves.
4. Note that regulating temperature and illuminating with ultraviolet light are functions related to other types of microscopes or additional equipment, not the lenses in a brightfield microscope.
5. Conclude that the lenses' main function is to magnify the image of the specimen, allowing detailed observation.
