Question

Which of the following hormone is associated with phototropic movement?
  1. Gibberellin
  2. Auxin
  3. Abscisic acid
  4. Cytokinin


Solution

The correct option is B Auxin
Auxins are synthesized at the shoot tip and help the cells to grow longer. When light is coming from one side of the plant, auxin diffuses towards the shady side of the shoot. This concentration of auxin stimulates the cells to grow longer on the side of the shoot which is away from light. Thus, the plant appears to bend towards light. This ability of a plant to grow in the direction of light is called phototropism.
