How do plants reproduce? Pollination is a term used to describe the transfer of pollen grains from the stamen to the pistil. The stamen consists of two major parts, the anther attached to a thin filament. Pollen, male gametes, is produced in the anther. Wind, animals, and insects help transport the pollen to the sticky tip of the pistil called the stigma. The pollen can travel through the style to a hollow structure called the ovary. The ovary contains one or more ovule. The female gametes are inside the ovule. Fertilization occurs within the ovary when the male gametes combine with an egg inside an ovule. The fertilized egg can grow and develop into the embryo portion of the seed. Cross pollination takes place when two different plants are involved in fertilization.   The flower has been self-pollinated when the pollen and egg are from the same plant.
