How do flowers get their smell?

Two pages possibly helpful. Basically there are different chemicals produced by plants which make their fragrances.

Anthony R. Brach

Flowering plants produce volatile chemicals that evaporate into the air and produce their fragrance (pleasant or sometimes unpleasant -- at least to humans). Presumably, this is to attract pollenating insects, but this is not necessarily so, because we don't know that insects "smell" the same way humans, or even other animals, do.

You raise an interesting question that I don't have an answer for: "Why do humans find the fragrances of most flowers pleasing? What in our evolutionary process for both humans and for flowers makes this rather universal connection favorable to survival, assuming there is a connection." Hmmm--a very interesting subject for a research paper for you in your science class, or even a class project.
