because an oak leaf is too thick to see the cells through a microscope. The light can not go though.
because the thinner it is the clearer it is too see inside
A dissection microscope is called a stereoscopic microscope. It has low magnification that is useful for viewing large, thick objects.
Plasma membranes are not dense enough to be seen clearly with a transmission microscope without some sort to staining procedure. A phase-contrast microscope (also light microscope, but with slightly different optics) is the usual tool, especially for cultured cells. http://www.answers.com/phase+contrast+microscope
The Milky Way spiral galaxy is about 100,000 light years in diameter, and about 3,000 light years thick at its center, and about 1,000 light years thick near its outer edge.

Light microscope works because light goes *through* your specimen. So if the specimen is too thick, then light won't shine through, and you won't see anything.
With a normal light microscope, you can't look directly at your finger. It's just too thick for light from underneath to pass through, to reach the microscope lenses. It might be possible to scrape off thin layers of dead skin and put them on a slide to view through a microscope, though.
You would expect to see a silhouette of the figure because it is too thick. -Franceska Biology Major
the light from the lamp below the table would not get through the sample, meaning it could not be seen or analysed.
The light is reflected upwards, and passes through the specimen. It passes through easier (clearer) if the specimen is not too thick.
Yes it is, if it is thick enough so that no light makes it through. Under ordinary circumstances, wood is opaque.

The definition of "transparent" is, "allows light to pass through". Regardless of width, an object can only be transparent if its composition allows light to pass through. The other criteria is thickness. Even if the object is made of glass, if it is thick enough it will not be transparent. You will not be able to see through it although some glimmer of light may reach all the way through and appear, usually as a pale green glow.
only at the time of cell division in the metaphase and in the anaphase the chromosome are visible. because at this time the chromatin get aggregate and form the thick chromosome which are visible under microscope.
dissecting scope: view opaque and/or thick objectsExamples: rock samples, coins, insects, and flowers
