Pollination refers to the transfer of pollen from anther to the stigma of a flower. 

Geitonogamy-Transfer of pollen from anthers of one flower to the stigma of another flower of the same plant. 

Xenogamy- Transfer of pollen from anther to the stigma of another flower of a different plant. 

Dichogamy- It is an outbreeding device, to prevent self-pollination here anther, and stigma matures at different times.

  1. Protandry-In this anther matures first than the stigma of the same flower, so pollen is transferred to another flower. E.g. Sunflower
  2. Protogyny-In this stigma matures first than anther of the same flower. E.G.-Mirabilis jalapa

Dicliny- Flowers are unisexual so self-pollination does not take place. It is also an outbreeding device to prevent self-pollination.
