Question

Name the hormone which is responsible for the phototrophic movement of plant

Answer 1

Answer:

The plant hormone Auxin is responsible for the phototrophic movement of the plant.

• Auxin is a phytohormone which helps in the cell division.

• The phototropic movement is a tropic movement which happens because of the stimuli - Sunlight.

• When senses the light in a direction, it produces auxin.

• The auxin molecules are more produced at the side of the plant which is away from light.

• The auxin then divides the cells at that side at faster rate because of the concentration of the hormone, leading to the bending of a shoot in the direction of of sunlight.
