When a horizontally positioned plant responds to gravity,

auxins in the lower sides of stems cause cell elongation that bends the stem upright.
the shoot bends to grow downward, toward the force of gravity.
all parts of the plant bend upward, away from the force of gravity.
auxins in the shoot cause the growth of tendrils to pull the shoot upwards.
