Pollination and sexual reproduction in plants

Hi,

Pollination involves flowers and pollen grains. The agents of pollination could be insects such as bees, ants, bats and other animals that visit flowers to get their food- pollen grains and nectar.

After the pollen grain is successfully transferred from the anther to the stigma, fertilisation process will kick in. This process is different from that in animals as the pollen grain germinates and grows a pollen tube will allows the male gamete to travel through the tube to the ovule.

Flowers go to great lengths to avoid self-fertilisation and prefer cross-fertilisation. It is fascination to see this processes employed in the different species of flowering plants.
