You Grew Reed Canary Grass Seedlings in the Dark and Cut

You grew reed canary grass seedlings in the dark and cut off their tips. You then placed the tips on agar blocks, one in dark and one in light. Based on your knowledge of auxin movement and stability in light, predict the concentration of auxin in the agar blocks.

A) The block in the light should have more auxin; the one in the dark will have less.
B) The block in the dark should have more auxin; the one in the light will have less.
C) The block in the dark should have some auxin; the one in the light will have none.
D) The block in the light should have some auxin; the one in the dark will have none.
E) Both blocks will have an equal amount of auxin.
