  • Adaptation for cross-pollination is unisexuality and dichogamy. 
  • In unisexual flowers, stamens and carpels are borne in different flowers either on the same plant or in flowers borne on separate plants ensuring cross-pollination. 
  • In dichogamy, stamens and carpels in a flower do not mature at the same time and hence selfpollination is eliminated. 
  • When pollen grains are transferred to the stigma of the flower on the different plant it is called Crosspollination or Allogamy. 

Two adaptations for cross-pollination: 

Xenogamy: Pollen grains of a flower is transferred to the stigma of a different flower on a different plant of same species. 

 Hybridism: Pollen grains of a flower is transferred to the stigma of a flower of a plant of different species.
