Hey are you asking if that's correct? Or how your sons homework will be marked? 

Anyway, yes we use dyes, that usually change colour when they come in contact with specific molecules. Though I'm not too sure of the specifics.

Okey doke :) well this website has a good list of cell stains: http://serc.carleton.edu/microbelife/research_methods/microscopy/index.html This one is pretty common to be used when you're learning about stains: Iodine - used as a starch indicator. When in solution, starch and iodine turn a dark blue color.
