Round 8: 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 (10[1])of homeotic genes in the ABC (10[1])model. (10[1])Entomophilous (10[1])(“en-toh-MOFF-il-us”) examples of these structures co-evolved ultraviolet patterns to advertise themselves. The ability to bear fruits and (10[1])these structures is shared by all angiosperms, whose common (10[2])name references these structures. (10[1])Hermaphroditic, or perfect, examples of these structures contain both stamens (10[1])and carpels. For 10 points, name these plant reproductive structures that attract pollinators with their colorful petals. ■END■
