29
supports the stage and condeser lens
arm
30
used to focus the light from the lam through the specimen
condenser lens
31
adjusts the height of the condenser
adjustment knob
32
controls the width of the circle of light, and the amount of light passing through the specimen
iris diaphragm
33
supports the specimen to be viewed
stage
34
features that can move the stage back and fourth and left to right
stage adjustment knobs
35
feature that allows for the intensity of light to be adjusted
light intensity lever
36
Coarse focus knob
moves the stage dramatically up and down
37
Solution to problem: when changing the magnification from 10X to 40X, the specimen dissapears
you should change the ocular lens back to 10X and center the specimen
38
Solution to Problem: The field of view is too dark
light intensity knob is turned to low
the iris diaphragm is not open enough
39
Solution to problem: You are not seeing the details in your specimen or are not able to identify structures that you hace been asked to recognize
fine foucus, course focus, change lens
40
/structures that distinguish a plant from an animal cell
cell walls, chloroplasts, nuclear nuclear envelope?
