I work in a flower shop! Do you like flowers?
Yeah I've always been a fan of gardening and different types of flowers!
What exactly is the purpose of a flower, I often wonder...
Well flowers are actually the reproductive structure of flowering plants!
Flowers can reproduce? To which purpose? I must be the worst flower shop employee!
It's fine, but yes they can reproduce! Essentially fertilization occurs and then a fruit is developed! 
That is beautiful! What is this process called?
I don't believe there is any unique name for the fertilization of flowers, honestly.
