Cells come from existing cells. Cells are the basic unit of life. All living thing have cells
Cell theory
Supports the body tube
maintains distance between eyepiece and objectives lenses
Body Tube
Shines on slide
moves the stage up and down to slightly sharpen the image - use after the coarse adjustment knob
Fine adjustment Knob
moves the stage up and down for focusing - be careful when using on high power b/c you can crush the slide
Coarse adjustment Knob
A organelle that contain chemicals that break down large food particles into smaller ones
A thin flexible barrier that surrounds a cell and controls what goes in and out of a cell
Cell membrane
Stores water, food, and other materials needed by the cell
A rigid supporting layer that surrounds the cell of plants and some other organisms
Cell wall
An organelle in the cells of plants and some other organisms that captures energy from sunlight and changes it to an energy form that cells can use in making food.
In cells, a large oval organelle that contains the cells genetic material in the form of DNA and controls many of the cells activities
Produce protein
The thick fluid region of a cell located inside the cell membrane and nucleus.
An organelle in a cell that receives protein and other newly formed material from the endoplasmic reticulum, packages them, and distributes them to other pants of the cell.
Golgi body
The flat platform where you place your slides. Stage clips hold the slides in place. If your microscope has a mechanical stage, you will be able to move the slide around by turning two knobs. One moves it left and right, the other moves it up and down.
the lens at the top that you look through. They are usually 10X or 15X power.
Eyepiece lens
Metal clips that hold the slide in place
Stage clips
Controls amount of light entering the body tube.
Holds high and low power objectives, can be rotated to adjust magnification.
Revolving nosepiece
Provides magnification times 40
High objective
