Part Name
Purpose of Part 1
Look through this to see an object under the microscope. Usually 10X magnification. 2
Connects the ocular to the microscope. 3
Connects the base and the barrel. 4
Turns to change the objective lenses to use. 5
Holds the slide in place 6
Used to view objects at three different magnifications 7
Moves the stage side-to-side, or forward and back to get the object into the field of view

8. Vacuoles Larger in plants than animals Function
Storage of food and water and waste

9. Vacuoles
When a plant cell has stopped growing there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell's VOLUME. The vacuole holds large amounts of water or food. The vacuoles can also hold the plant waste products.

10. Chloroplast

11. Chloroplast Structure
Contains chlorophyll and enzymes required for photosynthesis
Contains ribosomes and a small loop of DNA

12. Chloroplast Function Production of carbohydrates - glucose
6CO2 + 6H2O  6O2 + C6H12O6 (glucose)
The process of producing these carbohydrates is known as photosynthesis

13. Cell Wall

14. Cell membrane vs. Cell wall
Structure
Found in plant cells, made of layers of cellulose
Function
Support and protection of the cell

18. How To Use a Microscope
Make sure the objective lens with the lowest power is in place.
Place the slide on the stage and secure the slide using the stage clip.
Use the coarse focus knob to bring the objective lens close to the slide. Use the fine focus knob to focus.
To move to high power, rotate the nosepiece to the high power objective lens. Use the fine adjustment knob to bring the image into focus.
