How can pollen be dispersed?

Pollen is the product of the male reproductive system of a plant and needs to be dispersed, ideally, away from the parent plant. This pollen dispersal increases genetic diversity, protects the species from extinction and reduces the competition between the plants for resources. A number of agents are used for the dispersal of pollen. Many flowering plants use bees and other insects for pollen dispersal. Some other plants may use birds for pollen dispersal. These...

Pollen is the product of the male reproductive system of a plant and needs to be dispersed, ideally, away from the parent plant. This pollen dispersal increases genetic diversity, protects the species from extinction and reduces the competition between the plants for resources. A number of agents are used for the dispersal of pollen. Many flowering plants use bees and other insects for pollen dispersal. Some other plants may use birds for pollen dispersal. These pollinators (the organisms that causes pollination by dispersal) need to be attracted towards the pollen source. That is why many plants produce nectar. Wind and water are known agents of pollen dispersal. Wind can carry the pollen great distances. Similarly, any pollen that falls into water can also be carried away to distant regions. This increases the chance of pollination of a flower farther away, increasing the odds of the seedlings growing in some region far away from the parent plant. This will give both plants greater access to resources without competition between the parent plant and seedling.

Hope this helps.
