For sexual reproduction to take place,the pollen grains from the male part must land on the female part so that the egg can be fertilised.
Pollen is powder-like and each pollen grain is small and light. It can be carried by wind or insects from the anther to stigma of the same or another flower. The transfer of the pollen from the anther to the stigma is called pollination.
Insects, such as bees, butterflies and moths, are important pollinators.
Flowers which are pollinated by insects usually have colourful petals or pleasant scent to attract the insects. The insects are usually rewarded with nectar in the flowers.
