the only way you can visualize the vaces because they're too tiny to be visualized by standard microscopy labeling with florescent dyes is about the only way we can um easily identify what molecules have been passed down from the vesicles to The Germ cells but that's very restrictive you see because there will be millions of different molecules in a single visle to be faced with only being able to label three or four of those otherwise we can't make out the the differences is it's very tedious
