Flower Dissection

Parts of a Flower

The flower is the reproductive organ of a flowering plant. The male part of the flower is the stamen, which is composed of an anther supported by a filament.  The anther produces pollen.  Each pollen grain contains a male gamete (sperm nucleus).  The female part of a flower is the pistil, which is composed of an ovary, style, and stigma.  An ovary contains one or more ovules.  Each ovule contains a female gamete (egg nucleus).  The style supports the stigma.  The stigma produces a sugary secretion to which pollen grains stick during pollination.
