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