Introduction: A natural response for a plant receiving sunlight on one side of the stem will trigger a response that will release Auxin to the darker side of the plant. Auxin will promote cell elongation on the dark side of the plant causing the plant to bend towards the light. It is because of phototropism. Darwin grew grass seedling where the light all around it. Then the result was the coleoptiles elongated straight. And the …

…It can prevent the high concentration of Auxin inhibit the cell elongation and then we got the result that the plants without auxin grow faster than the plants with auxin control. In this experiment we learned that Auxin can stimulates plant growth through cell elongation, plants grow higher in the dark in an attempt to reach sun light, high concentration of Auxin inhibit cell elongation and sunlight is one of the important element for photosynthesis.
