Iodine solution is used as a stain to see various organelles clearly.
Iodine will help many cells which are difficult to see become more visible. When the iodine contacts the oxygen in the cell, that portion turns black making the sample more visible.

Starches and (maybe) Gram-positive bacteria.
An oak leaf would not make a good specimen for a wet mount because it contains a lot of water. The leaf is best observed under a dry mount.
Increase the magnification
because in a dried smear the size of the microorganisms reduce by almost 10 to 20% from the dimensions of the living microorganism.

The benefit of a wet mount is that you can view the specimen in its natural environment without killing it. If you do a wet mount you can get proper air around the microbes to view them for a while before they possibly die. If you do a hanging wet mount you have the capability to see them moving in an aerated manner.

An Iodine Flask is essential an Erlenmeyer Flask with a stopper used for the wet chemical analysis "Iodine Determination" . This analysis is typically performed on fatty acids, oils and shellac varnishes.

They took ash from Mount Vesuvius and mixed it with wet lime to make a kind of concrete that was also used for constructing the Colosseum in Rome, Italy. The way the Colosseum is still holding up is because they used this kind of material to make this concrete.
Wet mounts allow one to view living material versus dead material.
mount thats wet. :trollface:

It is to make sure that you know how to make a wet mount. At least, in honors biology it is
