Microscopy

Microscopy is a technical field of study about the use of microscopes to observe small objects like cells and micro-organisms that are not visible to the naked eye. A microscope is used in the field of microscopy, in order to see the object or organism that cannot be seen easily. Microscopes help us to observe the fine structure of a cell and its content.
