The protons are being released through the chemosmosis process and then go into the soil, and the negatively charged clay particles get stuck to the root hair. Clay favors protons over cationscations get released into the root hair and soil. This process of exchanging protons for these minerals would never happen if it wasnt for the chemeosmosis thing. Why do plants die with too much water they suffocate because they cant do respiration which forms ATP to pull in all the minerals. All this water, where does it go they go into the xylem. All the water containing the minerals has to get into here. IT ends up there the xylem. Short distance transport of water form xylem to root hair Root hairs have cell wall the water enters through the cell wall and stays in the apoplast, and it stays there.
