Available September through May in school library issues of Virginia Wildlife magazine or on the Web. The first step in plant reproduction is the intricate process called pollination, which occurs when pollen grains, the male germ cell of a plant, reach the stigma, the female reproductive part of the same species of plant. Depending on the plant species, a flower can produce male, female, or both structures.
Pollination can also occur within the same flower.
The female reproductive part of a flower is receptive to pollen only at certain times of the year. Creatures like insects and birds, which move from flower to flower in search of food, are a fast and often guaranteed way for plants to distribute their pollen. The plant has secreted nectar, a concentrated food source, from special glands and tucked it away in its blossom. While crawling around the blossom looking for nectar, the pollinator rubs against the pollen, which becomes attached to different parts of the pollinator's body. When the pollinator visits another blossom, it transfers the pollen grains from its body onto a strategically placed stigma.
