Packet H: Bonus 4
Compounds produced by this genus were shown to induce starvation responses in Drosophila despite insects lacking their CB1 and CB2 receptors. For 10 points each:
[10e] Name this genus whose sativa species secretes a “phyto” class of compounds for chemical defense against herbivores. This genus names a group of drugs whose active compounds include CBD and delta-9-THC.
ANSWER: Cannabis [accept cannabis drugs; accept Cannabis indica or Cannabis ruderalis; accept cannabinoids or phytocannabinoids or endocannabinoids; prompt on C. sativa or C. indica or C. ruderalis; reject “marijuana”]
[10h] C. sativa secretes cannabinoids from the glandular form of these hair-like structures. Contact with these structures in Drosera and Pinguicula plants triggers a nastic response that causes their leaves to curl around prey.
ANSWER: trichomes [accept glandular trichomes; prompt on outgrowths or appendages or prickles or emergencies or scales or tentacles]
[10m] Glandular trichomes store defensive secondary metabolites in neck strips composed primarily of this material. This complex phenol-rich polymer provides structural rigidity and hydrophobicity to plant cell walls.
ANSWER: lignin [prompt on lignocellulose]
