Daisies are related to sunflowers, asters, coneflowers, dandelions, and chrysanthemums. The flower center is made up of hundreds of tiny disk florets which produce the seeds. They are arranged in a beautiful swirling pattern that has some complicated mathmatical formula, I'm sure. But I think I'll just enjoy them for their beauty. The disk florets are surrounded by the ray florets, what we think of as the petals.
