When bacteria are stained, it is because the stain ions react with cell structures that have the opposite ionic charge (+ and - are attracted to one another). Use outside resources to find out this information: What cell structure(s) is(are) stained by the dye to give this organism the color observed?

Please I would like to know the resource too!
