Magnification
Is the degree to which the size of an image is larger than the object itself.

Resolution
Is the degree to which it is possible to distinguish between two objects that are very close together. The higher the resolution the greater detail you can see.

Staining
Staining in microscopy refers to any process that helps to reveal or distinguish different features. In LIGHT microscopy, stains may be colours or fluorescent dyes. In electron microscopy, they are metal particles of metal salts.
