The male component of a flower, the anther, is used to collect pollen grains, which are then transmitted to the female component, the stigma. The pollen grains must be transmitted from the same species of flower for pollination to be successful.
Self Pollination :
As it involves just one flower, it is known as the main kind of pollination. When pollen grains fall straight from an anther into the stigma of the flower, self-pollination takes place. Given that the sperm and egg cells of the flower share some genetic information, this straightforward and quick process reduces genetic variety.
Cross Pollination :
It alludes to a sophisticated form of pollination that enables the transport of pollen grains from a flowers anther into its stigma. As a result of sharing and combining their genetic information to produce distinctive offspring, this strategy increases genetic variety.
Procedure of Pollination :
The pollination process starts when pollen grains from the corresponding flowers land on the stigma and join with the style length to produce a pollen tube that connects the stigma and ovary. The pollen grain begins transporting sperm cells from the grain to the ovary after the pollen tube has been fully formed. When the sperm cells reach the ovary and egg cells, the process of plant fertilisation will begin. Using the pollination method, the seed is then dispersed from the parent plant, enabling it to develop into a plant and carry on the reproductive cycle.
