Question

NAME THE HORMONE WHICH IS INVOLVED IN PHOTO TROPISM?? EXPLAIN ITS ROLE??​

Answer 1

Answer:

The hormone responsible for phototropism is Auxin. Auxin is a plant growth regulator which is produced by growing apices of stems and roots. When light falls on the plant, auxin moves away from the light. Therefore, the concentration of auxin increases on the shady side of the plant.
