6.There are two kinds of sunflower seeds. Oil is made from black seeds and snacks are made from striped seeds.

7.The daily orientation of the flower to the sun is a direct result of differential growth of the stem.

Because of this accumulation, the darker side grows faster than the sunlit side. Thus, the stem bends toward the sun.
