A scientist wants to observe how a plant reacts to a certain type of auxin hormone that the plant naturally produces. She places a small patch that releases auxin on one side of a plant. She places the plant in a room where light shines on the plant in all directions. A drawing of the plant before the experiment and after a week of the experiment is shown below. Refer to the plant auxin experiment above. How did the plant respond to the auxin stimulus?

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.
