An agar block filled with auxin is placed on top of a shoot that has had the shoot tip removed. the agar block is placed so that it covers only one side of the top of the shoot. you would expect the shoot to
a. grow straight up
b. stop growing
c. grow faster on the side away from the agar block
d. grow faster on both the side away from the agar block and on the side with agar block
e. grow faster on the side with the agar block

The shoot would be expected to grow faster on the side with the agar block.

Explanation:

According to the experiments conducted by Went, the shoot is growing on the side with the agar block as it is responding to the chemical spread in the shaded part of the plant. This will make the shaded portion bend towards the light.

The auxin is damaged by light. There would be uneven auxin distribution if more light comes from only one side. More auxin will be on the shaded side than side in the light . The shaded side will grow faster resulting in the shoot growing towards the light.
