What is believed to be responsible for the detection of gravity in roots and shoots?

    Plastids settling onto the lowest surface of the root/shoot (i.e., furthest away from the surface of the soil) initiate a series of steps that end with auxin triggering an unequal elongation in the root/shoot.
    Auxin itself is able to detect the direction of gravity.
    Both the first and second answers are correct.
    none of the above
