Some types of stains are called vital stains. Methylene blue is picked up by living cells, but not dead cells. Trypan blue is picked up by dead cells, but not living cells. By using vital stains in wet mount, you can tell live cells from dead cells.

Unstained Cells

When you look at a stained cell you can easily see the components of the cell. You should be able to see the cell wall, chromosomes, nucleus and mitochondria. In an unstained cell it would be very difficult to differentiate the components of the cell. At least that's what I remember from high school, anyway.

Basically biologists use stains to see things easier - they introduce what's basically a dye that attaches to certain bits of the cell - like introducing iodine that highlights starch in a plant cell. There's different dyes depending on what you're looking at, common ones used on animal cells will show cell outlines via colouring various proteins. it's a bit like colouring in a stained glass window to see the picture.
