A figure-reading aid for the 2013 Osedax research. Use the published microscopy, rather than treating the illustration as measured anatomy.
| Region | Question for the paper |
|---|---|
| Visible plume | What is exposed above the bone? |
| Root epithelium | Where was the proton-pumping machinery localized? |
| Root interior | Where are symbiotic bacteria described? |
| Bone interface | Which proposed chemical step makes nutrients accessible? |
Finding a protein somewhere in the animal is different from locating it at the surface contacting bone. Localization strengthens a mechanism, but the complete nutrient route still requires multiple kinds of evidence.
