Plant Reproduction
... Plants with flowers reproduce sexually. This happens when pollen from the stamen reaches the pistil. Pollination is the transfer of pollen from the male part to the female part of flowers. Some plants self-pollinate. The pollen comes from the stamens of the same plant. Other plants cross-pollinate. ...
