The connective where the second cell may or may not exist then functions as a kind of lever that pollinators push against as they enter the corolla tube searching for pollen or nectar.
The stamens in flowers of the vast majority of plants consist of two bag-like, pollen-producing cells side by side, like two frankfurters side by side at the end of a stick.
Description: One cell on one end of the connective produces pollen normally but the other cell at the connective's opposite end is either rudimentary or completely lacking. Everything looks similar except the flowers, and they're very different.
