The paramecium seemed to move faster at a higher magnification because moving 2 microliters under a 4x optical zoom in 1 second is like moving 4 r. u. in 1 sec, but moving 2 microliters under a 10x optical zoom in 1 second is like moving 10 or 20 r. u. in 1 second. This makes it look as if the paramecium is moving faster because the zoom is greater. 7. Since paramecium is see through and has it’s own medium, the light

Unformatted text preview: passing through it is refracted as well as absorbed. Therefore, its shape and color are visible through the brightfield microscope. 8. The I2 + KI does two things; it stains the paramecium to make it more visible and also it kills the cells so they are easy to view and stay still. 9. Yes, I believe they are the same species because though they were different colors, they have the same anatomy and sizes. 10. Wet mounts are more interesting because the species is normally moving and shown in its natural environment as opposed to dry mounts. Though permanent dry mounts are easier to see and evaluate 11.
