The reason is that most microorganisms live in some type of water medium and most that do not can still move and survive in it. The wet mount tend to dry out quickly under the heat of the microscope light; it is simpler to perform than the wet mount, but it is useful for short-term observation only. Improper adjustment of the microscope in relation to the objective may create problems. The simplest type of preparation is the wet mount, in which the specimen is placed on the slide in a drop of liquid. In a wet mount, a drop of water is used to suspend the specimen between the slide and cover slip.
