Explanation:

                          AGENTS FOR CROSS POLLINATION

Plants need to have some agents for pollination.They could be abiotic like wind and water or biotic like insects,birds or bats.

 WIND POLLINATION : In this type of pollination plants literally fill the air with pollen when stamens mature.The pollens are carried to hundreds of kilometers away by wind.

         Example : plants like coconut plam , date plam,cannabis,maize etc.

WATER POLLINATION: In this type of pollination,the pollen grains are carried by water and when they reach the stigma,they coiled it and germinate.

              Example : plants like Vallisneria,Ceratophyllum hydrilla, Zostera marina etc.
