Where are these chemicals made in a flower?
These carbohydrates, or simple sugars, are produced by the nectaries.
What is the name of the chemical reaction that produces the chemical components of nectar?
Photosynthesis.
Which structure, in this photograph, is responsible for making pollen?

Which part of the flower will pollen stick to in order to complete pollenation?
