Pollen refers to the powdery product synthesized by seed plants responsible for the production of the male gametes of the plant (shown below).PollenThe pollen grains are termed microgameteophytes, and consist of a sporopollenin coating which serves to protect the gameteophytes as they are transported from the stamens (male) or male cone to the pistil (female) or female cone in flowering and coniferous plants, respectively. When the pollen reaches the pistil or female cone, a pollen tube is formed, which transports the sperm to the ovule containing the female gametophyte. The term pollination refers to the transfer of pollen grains from the anther to the stigma of a flower. Cross-pollination involves the transfer of pollen from one flower to the stigma of another flower. In contrast, self-pollination involves the transfer of pollen from one flower to the stigma of the same flower. A diagram illustrating the location of the anther and stigma is shown below.
