    Because it is a mature red blood cell, and remember red blood cell doesn't have nucleus,mitochondria.... just read the solution part....

    b/c lysosomes are very dark because of a specific stain that reacts with one of the products fo digestion within the lysosome. -campbell bio book

    ok that mkaes sense.....however for if the "circle" was clear instead of dark would it be considered a nucleus...i guess what im saying is what would it have to look like for it to be a nucleus

    It would not by white because the dye stains acidic organelles dark. The nucleus is acidic because of the nucleic ACIDS. It would probably be less dark and patchy and also with nucleolous.

    I don't know about that!!!! I have destroyer December 2007 edition and the question still says a mature red blood cell. Probably if you have an older edition could be a typo...... if not the explanations written here are very good.
