Round 5: 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. (10[1])Entomophilous (“en-toh-MOFF-il-us”) examples of these structures co-evolved ultraviolet patterns to advertise themselves. The ability to bear fruits and these (10[1])structures (10[1])is shared by all angiosperms, whose common name references these structures. Hermaphroditic, or perfect, examples of these structures contain both stamens and carpels. For 10 points, name these plant reproductive structures that attract pollinators (10[1])with their colorful petals. ■END■
