Why would you use a light microscope?

Microscopes are used to produce magnified images. … light microscopes are

used to study living cells

and for regular use when relatively low magnification and resolution is enough. electron microscopes provide higher magnifications and higher resolution images but cannot be used to view living cells.

Why do cells need to be stained prior to microscopy?

The most basic reason that cells are stained is

to enhance visualization of the cell or certain cellular components under a microscope

. Cells may also be stained to highlight metabolic processes or to differentiate between live and dead cells in a sample.
