we use sterile water because to avoid false result by microorganism having in the water and same reason for distilled also to avoid impurities like crystals of some metal ions and also to avoid other microorganisms
specimins are sometimes stained so that you can see them more clearly under a microscope. for example: if a specimin was clear or semi-transparent, then it would be stained with dye so that when you examine it you can see it, but if it wasn't stained then the light would just shine right through it and you wouldn't see al the features clearly.
why are specimens to be stained suspended in sterile saline or distille water

The general term is 'stain' of which there are several chemicals that can be used, depending on the specimen.
It would be the color you stained.
to minimize effects of platelet clumping
The clinical specimens that are gram stained are microorganism, bodily fluids and sputum specimen. Gram staining makes it easier for the identification of organisms.
That is not the case; you are looking at how some dissection specimens have had their veins and arteries stained. It is the dyes used in the preparation of the specimens.

Stains.
Biopsy specimens are often sliced into thin slices, stained, mounted on a glass slide, and examined using a light microscope. Newer sample preparation techniques involve the rapid freezing of the sample and slicing of the still-frozen material.
may get infections.because in labs we use decayed specimens for testing.moreover our food item too can contaminate the specimens sometimes or may change its properties.
No. Not unless it is damaged or stained. And sometimes not even then.
To see them better
In a typical cell the cell wall gets stained most. But sometimes even the nucleus gets stained but more specifically the chromatin material in the nucleus.
