Why must samples to be used under a microscope be sliced very thinly?

• So you can get more slices from each sample.

• So light can pass through the slice.

• Because the cover slip won't lie flat over the slice.

• It is standard procedure in microscopy.

What is the purpose of differential staining?

• To make the whole specimen easier to see

• To highlight specific cell structures and make them more visible

• To make the stained tissue appear sharper, increasing resolution

• To reduce deflection of light

How should a microscope be stored?

• with the low power objective in place

• without a dust cover

• with the stage fully raised

• with microscope slides secured to the stage
