GinnyAnswer

Final answer:

Positively charged chromophores in basic dyes allow them to penetrate cells by sticking to the negatively charged cell walls.


Explanation:

Positively charged chromophores in basic dyes allow them to penetrate a cell because cells typically have negatively charged cell walls. This attraction causes the basic dye to stick to the cell walls, making them positive stains, such as methylene blue, crystal violet, and malachite green.
