Answer:

Nucleus

Explanation:

Methylene blue stains negatively charged molecules in the cell, DNA and RNA are both abundant negatively charged molecules present in the cell nucleus. This means, the nucleus will appear dark blue having taken up most of the stain. The rest of the cell will be a light blue colour, where some of the stain is picked up
