In some species, such as magnolia, sepals look like petals, and both are collectively called "tepals:' Suggest an extension to the ABC model that could hypothetically account for the origin of tepals.
. WHAT IF? If flowers had shorter styles, pollen tubeswould more easily reach the embryo sac. Suggest anexplanation for why very long styles have evolved inmost flowering plants.
