A flower, sometimes known as a bloom or blossom.
The biological function of a flower is to effect reproduction.

Many flowering plants reflect as much light as possible within the range of visible wavelengths of the pollinator the plant intends to attract.
An important feature of white flowers is that they reflect equally across the visible spectrum. Color allows a flowering plant to be more specific about the pollinator it seeks to attract.
