Structures for ReproductionParts of the flowering plant that function in reproduction include:

Flowers • Flowers produce seeds. • Many flowers contain both male and female parts

• A fruit is formed from the ovary which protects the seeds.

• Seeds have special structures that allow them to be dispersed by wind, water or animals.
