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. |
