Why investigators need to stain cells?
We stain cells in different ways for different reasons. First of all, many cells and their parts are transparent and so don't show up under the microscope unless we stain them. Secondly, many stains react with the cells in different biochemical ways and this helps us to identify some organisms, for example, the Gram stain colors some bacteria purple and others pink.

Are the chromosomes visible through the microscopes used in school laboratories?
Depends a bit on how high power your microscopes are, but probably, yes. You'd need to catch the cells during cell division, however, and then stain with something like Giemsa to make the chromosomes visible for light microscopy. The cells would need to be in metaphase ie. with condensed chromosomes.

How do you get stains out of shirts?
Depends on the stain! I washed my son's blue tshirt a million times trying to get a chocolate stain out of it and finally tried hydrogen peroxide and rubbing alcohol! Worked like a charm! Greasy stains need dishwashing detergent. The key is to get to the stain ASAP and to NOT dry the garment in the dryer until the stain is removed. The dryer will set the stain!
