The purpose of pollen is to transfer the male reproductive cells (sperm) to the female reproductive cells (ovules) and thus to allow sexual reproduction. Pollen can be so transferred by many methods - wind, gravity, insects, etc. The pollen receptive part of the flower (the stigma) is often sticky, or textured so the pollen will stick. Once attached the pollen grain grows a tube into the stigma and down the style into the ovule. This tube allows the male gametes to fertilise the ovule, creating a seed.

When a flower is pollinated the grain of pollen falls were?
When a flower is pollinated, the pollen grain lands on the stigma of the flower, which is the female reproductive organ. The pollen grain then germinates, forming a pollen tube that grows down through the style to reach the ovary where fertilization can occur.

How does a pollen tube form?
A pollen tube forms when a pollen grain lands on the stigma of a flower and germinates. The pollen grain absorbs water and begins to grow a tube that will penetrate the style of the flower and reach the ovary. This is a crucial step in the process of fertilization in plants.
