🆕 New Concept Discovered: Microscope Selection
Choosing the right microscope based on specimen size and transparency.

Step 1: Understand the function of a dissecting microscope

A dissecting microscope (also known as a stereomicroscope) is designed for viewing large, three-dimensional, opaque specimens.

• It uses lower magnification (typically \(2\times\) to \(40\times\)).
• It provides a 3D view of the surface of an object.
• Light usually shines down onto the specimen (reflected light) rather than passing through it.

Step 2: Evaluate each sample option

• a lady bug: This is a relatively large, whole, opaque organism. A dissecting microscope is perfect for viewing its external features in 3D. (Select)
• carpel of a flower: This is a macroscopic, three-dimensional plant structure. A dissecting microscope is ideal for observing its surface details or dissecting it. (Select)
• Human cheek cells: These are microscopic, transparent, single cells. They require high magnification and transmitted light to be seen, which means they must be viewed under a compound light microscope. (Do not select)
• wing of a butterfly: This is a larger, flat, opaque structure with detailed surface scales. A dissecting microscope is excellent for viewing the intricate surface patterns of a butterfly wing. (Select)

Answer:

• a lady bug
• carpel of a flower
• wing of a butterfly
