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 (10[1])model. Entomophilous (“en-toh-MOFF-il-us”) examples of these structures (10[1])co-evolved ultraviolet patterns (10[1])to advertise (10[1])themselves. (-5[1])The ability to bear fruits and these structures is shared by all angiosperms, (10[2])whose (10[1])common name references these structures. (10[2])Hermaphroditic, or perfect, examples of these structures contain both stamens and (10[1])carpels. For 10 points, name these plant reproductive structures (10[1])that attract pollinators with their colorful petals. ■END■ (10[1])
