How do auxins cause plants to bend? A) Auxins make plant cells grow larger towards the light causing it to bend.

B) Auxins make plant cells grow heavier causing it to tip on one side.

C) Auxins cause plants to grow wider.

D) Auxins cause plant cells to shrink on one side making it less heavy, which tips the plant on the other side.

A.

Auxins make plant cells grow larger towards the light causing it to bend.

Explanation:

The auxins go more in the shady side, and that is why there are more auxins in the shady side, but in the illuminated side, there are less auxins. That will cause a bend in the growth of the plant towards the light source because the shady side has more auxins to make it grow. This is the reason why when there are auxins in a plant, they start to grow towards light.
