Are prokaryotic or eukaryotic cells easier to view in a wet mount and why?

Cells are better seen in humid environments since 80% of their composition is water.

Explanation:

These cells have most of their composition made up of water, that is why when viewed in humid environments they maintain the micro and macrostructure of both the cell and the organelles.

This is how the structures of these cells are best perceived, it depends on their sizes if an electronic or optical microscope is used.

It should be only once that an interphase occur before mitosis. It  is the phase of the cell cycle in which a typical cell spends most of its life. During this phase, the cell copies its DNA in preparation for mitosis. Hope this answers the question. Have a nice day.
