Making Scents: The Aromatic World of Flowers
>>Each scent compound from a flower is an organic molecule known as a volatile.
>>Each odor molecule has a spine built of carbon atoms.
>>Orchids have scent glands called osmophores that ooze liquid scent which evaporates upon air contact.
>>Plants must generate enough smell to induce insects to fertilize flowers, but not so much that they waste energy and carbon.
>>Some flowers have evolved to mimic the scents of other flowers but give no benefit to pollinators.
>>Some flowers can mimic the scent and look of animals like bees, flies, and scarab beetles.
