Pollination. Pollination is a way of reproduction for flowering plants. The word comes from the word pollen, which is basically the sperm of the plant. The pollen makes contact with the plantâs stigma and then the fertilization process starts. It is basically what sex is to plants. The process of pollination was actually discovered in the 18th century by a man named Christian Sprengel.
