Why is it necessary to stain bacterial cells?

It's necessary to stain tissues because they're otherwise difficult to see and some just blend in with backdrops underneath microscopes or the plates they're on.

Hi Nicole:)

Nice question.

You see bacteria can be differentiated into two different groups dependent on a simple staining procedure called Gram staining.

Cells that are stained purple by this procedure are Gram-positiv and thus have a thick cell wall of peptidoglycan, while cells that become pink/red have a thinner cell wall.

It can be very usefull to know of which of the two groups the bacteria belongs when diagnosting a patient fx as this would affect the treatment AFAIK.
