Question 1

In phototropism, how does the plant hormone auxin cause a seedling shoot to bend toward a unilateral light source?

Auxin migrates to the shaded side of the shoot, stimulating cell elongation on that side. Auxin migrates to the illuminated side of the shoot, inhibiting cell division on that side. Auxin is destroyed by light on the shaded side, causing the illuminated side to grow faster. Auxin concentrates equally on both sides, causing equal swelling of epidermal cells.

Correct Answer:

Auxin migrates to the shaded side of the shoot, stimulating cell elongation on that side.
