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.
Flowering Plants produce flowers for reproduction.The purpose of reproduction is to pass on their generations by dispersing the seeds by wind,water,splitting or maybe by animals or human beings.The female part of a flower consists of the ovary and stigma. The ovary has one or more ovules,each of which female reproductive cell called an egg(ovum).
The male part of a flower has a thin stalk with an anther at its tip. The anther is made up of pollen sacs which contain pollen grains. The male reproductive cells in the pollen grains can fertilise the eggs. A fertilised egg which can develop into a young plant.
In flowering plants,male reproductive cell joins with a female reproductive cell(egg) to produce a fertilised egg which can develop into a new plant. This kind of reproduction,which involves the union of a male and the female reproductive cell,is called sexual reproduction.
Sexual reproduction in flowering plants involves the following for processes: pollination, fertilisation, seed dispersal and germination.
