Description
Still life with sunflower.
The sunflower is native to North America and was used by the Indians for food and oil. Some farmers use it to feed their livestock.
The daily orientation of the flower to the sun is a direct result of differential growth of the stem. A plant-growth regulator, or auxin, accumulates on the shaded side of a plant when conditions of unequal light prevail. Because of this accumulation, the darker side grows faster than the sunlit side. Thus, the stem bends toward the sun.
