Let's solve the
"Parts of a Microscope Worksheet" by identifying each labeled part of the microscope in the diagram.
Here is the correct labeling for each numbered part:
---
1. Eyepiece (Ocular Lens)
- This is the lens at the top of the microscope that you look into. It magnifies the image produced by the objective lenses.
2. Revolving Nosepiece (Turret)
- The rotating part that holds the objective lenses. You can switch between different magnifications by turning this.
3. Objective Lenses
- These are the lenses located below the nosepiece. They come in different magnifications (e.g., 4x, 10x, 40x, 100x). They gather light from the specimen and produce the initial magnified image.
4. Stage
- The flat platform where the slide is placed for viewing. It usually has clips to hold the slide in place.
5. Stage Clips
- These are the small metal clips on the stage that secure the slide in position.
6. Diaphragm (Iris Diaphragm)
- Located beneath the stage, it controls the amount of light passing through the specimen. Adjusting it affects contrast and brightness.
7. Light Source (Illuminator)
- The light source at the base of the microscope that provides illumination for the specimen. In some microscopes, it’s a mirror instead of a built-in light.
8. Arm
- The curved support structure connecting the head to the base. It allows you to carry the microscope by holding the arm and base.
9. Body Tube
- The tube that connects the eyepiece to the objective lenses. It maintains the proper distance between them for clear focus.
10. Coarse Adjustment Knob
- The larger knob used to move the stage up and down quickly for initial focusing. Used with low-power objectives.
11. Fine Adjustment Knob
- The smaller knob used to make precise focus adjustments, especially when using higher magnification lenses.
12. Base
- The bottom part of the microscope that supports the entire instrument and houses the light source.
