Round 7: Tossup 20

Pseudocopulation with these structures is induced by Pouyannian mimicry, where these structures mimic a mate’s appearance. The development of these structures is described as the interaction of three groups of homeotic genes in the ABC model. Entomophilous (“en-toh-MOFF-il-us”) examples of these structures co-evolved ultraviolet patterns to advertise themselves. (10[3])The ability to bear fruits and these structures is shared by all angiosperms, whose common name references these structures. Hermaphroditic, or perfect, examples of these structures (10[1])contain both stamens and carpels. For 10 points, name these plant reproductive structures that attract pollinators with their colorful petals. ■END■
