07/00-- In snapdragon flowers, the upper and lower lobes emit floral scents, which attract bumblebees. To reach the nectar, a bee must move partially into the flower tube. When the bee brushes against the lobes of the flower, it picks up the flower's scent. The bee then carries the scent back to hive, attracting more bees to the plant.
