Why does a sideways root bend downward?
Fit the specimen and set conditions before running.
Dense statoliths settle in root-cap cells. The resulting lower-side auxin inhibits elongation there, so the upper side grows faster and curves the young root toward gravity.
Young primary dicot root; differential elongation=0.5 sin(tilt) mm/h, zone width 1 mm. Root-cap response dominates this model; weak alternate gravity responses omitted.
