Question

1. Give an example of Phototrophic movement ? ​

Answer 1

Sunflower is a highly phototropic plant. They grow towards the sun and are also seen tracking the movement of the sun throughout the day. That is, the flower keeps changing its direction with the movement of the sun. Sunflower requires more light for its growth and survival.

Answer 2

Answer:

Phototropic movements: Plants grow toward the sunlight to be able to generate energy by photosynthesis. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs.

This causes the plant to have elongated cells on the farthest side from the lightThe directional movement of plant part in response to source of light i.e. sun is called phototropic movement . the growth is towards the light stimulus. for example :- movement of stem in response to sunlight .Phototropism Examples
