Flower Power T is symmetry is easy to see inside an orange, too. Slice it in half and you’ll see. All the juicy sections stick out from the center of the fruit. You can see it in flowers, too. It’s easiest


to spot in round blooms, like dandelions or daisies. Like the sea star’s arms, the petals fan out in a circle from the centers. No matter how you turn these flowers, they look the same.
