Hello!
Does anyone know any technologies which trace the paths of elements through living plants and animals?
I need four, and so far I've got radioisotopes and aphids.
Thanks!

i dont remember doing this in prelim...hmm
you could say food dyes, although primitive it can be used to trace the flow of water and sugars in plant xylem phloem. its a common technique used to stain the vascular bundles before viewing under the microscope

ohh yeah, we did that in class.
i'm not sure if we can use that, but thanks anyway!

if you did it in class it should be fine to write it in an exam
ask anyway, your teacher might be a fag and be like "nuuuuuuuuuu"
