"vibrations can be strong enough to dislodge a seed’s 'statoliths,' which are tiny gravity-sensing organelles within certain cells of a seed." "Statoliths are denser than a cell’s cytoplasm and can drift and sink through the cell, like a bit of sand in a jar of water. When a statolith finally settles to the bottom, its resting place on the cell’s membrane is a reflection of gravity’s direction and a signal for where a seed’s root or shoot should grow." |
