Step-by-step solution for: Microscope Parts Labeling Activity | Storyboard That
The image you've uploaded is a labeled diagram of a compound light microscope, which is commonly used in biology and other sciences to magnify small objects or specimens. The diagram identifies and explains the key parts of the microscope. Let's go through each component and explain its function:
---
- Location: At the top of the microscope, where you look through.
- Function: This is the lens that magnifies the image formed by the objective lenses. It typically has a magnification of 10x.
- Explanation: When you look into the eyepiece, you see a magnified view of the specimen.
---
- Location: Below the eyepiece, mounted on a rotating nosepiece.
- Function: These are the lenses that are closest to the specimen. Most microscopes have three or four objective lenses with different magnifications (e.g., 4x, 10x, 40x, 100x).
- Explanation: By rotating the nosepiece, you can select different objective lenses to change the magnification. The total magnification is calculated by multiplying the eyepiece magnification by the objective magnification (e.g., 10x eyepiece × 40x objective = 400x total magnification).
---
- Location: The flat platform beneath the objective lenses.
- Function: Holds the slide containing the specimen.
- Explanation: The stage has clips or holders to secure the slide in place. Some stages are mechanical and allow for precise movement of the slide in X and Y directions.
---
- Location: Placed on the stage.
- Function: A thin piece of glass that holds the specimen for observation.
- Explanation: The specimen is placed on the slide, often covered with a coverslip, and then positioned under the objective lens for viewing.
---
- Location: At the base of the microscope.
- Function: Provides light to illuminate the specimen.
- Explanation: The lamp shines light upward through the specimen. In some older microscopes, a mirror may be used instead of a lamp to reflect light from an external source.
---
- Location: On the side of the microscope body.
- Function: Used to bring the specimen into focus.
- Explanation:
- The coarse focus wheel moves the stage up and down quickly to get a general focus.
- The fine focus wheel makes small adjustments for sharper, more precise focusing.
---
- Location: The curved part connecting the eyepiece to the base.
- Function: Supports the upper part of the microscope and serves as a handle for carrying.
- Explanation: The arm provides structural support and stability to the microscope.
---
- Location: The bottom part of the microscope.
- Function: Supports the entire microscope and houses the light source.
- Explanation: The base provides stability and keeps the microscope upright during use.

1. Light from the lamp passes upward through the slide.
2. The objective lens collects the light and forms a magnified image of the specimen.
3. This image is further magnified by the eyepiece lens.
4. You observe the final magnified image through the eyepiece.
5. Use the focus wheels to adjust the clarity of the image.
6. The stage holds the slide steady while you examine it.
---
- Total Magnification = Eyepiece Magnification × Objective Magnification
- Proper lighting is essential for clear viewing.
- Always start with the lowest power objective (e.g., 4x) when beginning observation to avoid damaging the slide or lens.
- Use the coarse focus knob first, then fine-tune with the fine focus knob.
This diagram is an excellent educational tool for understanding the structure and function of a compound light microscope. Each part plays a crucial role in enabling detailed observation of microscopic structures.

1. Eyepiece Lens (Ocular Lens)
- Location: At the top of the microscope, where you look through.
- Function: This is the lens that magnifies the image formed by the objective lenses. It typically has a magnification of 10x.
- Explanation: When you look into the eyepiece, you see a magnified view of the specimen.
---
2. Objective Lenses
- Location: Below the eyepiece, mounted on a rotating nosepiece.
- Function: These are the lenses that are closest to the specimen. Most microscopes have three or four objective lenses with different magnifications (e.g., 4x, 10x, 40x, 100x).
- Explanation: By rotating the nosepiece, you can select different objective lenses to change the magnification. The total magnification is calculated by multiplying the eyepiece magnification by the objective magnification (e.g., 10x eyepiece × 40x objective = 400x total magnification).

3. Stage
- Location: The flat platform beneath the objective lenses.
- Function: Holds the slide containing the specimen.
- Explanation: The stage has clips or holders to secure the slide in place. Some stages are mechanical and allow for precise movement of the slide in X and Y directions.
---
4. Slide
- Location: Placed on the stage.
- Function: A thin piece of glass that holds the specimen for observation.
- Explanation: The specimen is placed on the slide, often covered with a coverslip, and then positioned under the objective lens for viewing.
---
5. Lamp
- Location: At the base of the microscope.
- Function: Provides light to illuminate the specimen.
- Explanation: The lamp shines light upward through the specimen. In some older microscopes, a mirror may be used instead of a lamp to reflect light from an external source.
---
6. Focus Wheel (Coarse and Fine Adjustment Knobs)
- Location: On the side of the microscope body.
- Function: Used to bring the specimen into focus.
- Explanation:
- The coarse focus wheel moves the stage up and down quickly to get a general focus.
- The fine focus wheel makes small adjustments for sharper, more precise focusing.

7. Arm
- Location: The curved part connecting the eyepiece to the base.
- Function: Supports the upper part of the microscope and serves as a handle for carrying.
- Explanation: The arm provides structural support and stability to the microscope.
---
8. Base
- Location: The bottom part of the microscope.
- Function: Supports the entire microscope and houses the light source.
- Explanation: The base provides stability and keeps the microscope upright during use.
