A dry mount is exactly as it sounds: the thing you plan to observe is placed on the slide with a cover slip over it. No water is needed. This kind of mount is usually used for inanimate objects or things that do not need water to live.

What is the essence of wet mount in microscopy?

Wet mounting – live samples and specimens are fixed to a slide using water, a stain or other liquid. A cover slide is placed over the top and the sample is then ready to view. Fixing the specimen in this way also helps to keep the sample within the field of view once it is under the microscope.
