A plant on a windowsill grows straight when its pot is turned a little every day.
Which statement explains why?
Turning the pot moves auxin from the shoot tip down into the roots of the plant
Turning the pot stops the tip of the shoot from producing any auxin at all
Turning the pot lets the light break down auxin evenly on every side of the shoot
Turning the pot means auxin does not stay on one side of the shoot for long
