Why cannot fertilisation take place in flowers if pollination does not occur?
Pollination:- Transfer of pollen grain from the anther (male part of the flower) of stamen to the stigma (female part of the flower) of carpel is known as pollination. It is of two types- Self pollination (transfer of pollen grains from the anther to the stigma of the same flower or genetically similar flower), Cross pollination (transfer of pollen grains from the flower of one plant to the stigma of the flower of another plant). There are various agents which carries the pollination process like anemophily (wind pollination), hydrophily (water pollination), entomophily (insect pollination), ornithophily (pollination by birds) and chiropterophily (bat pollination).
Fertilisation:- Fusion of haploid male gamete (spermatozoan) and a haploid female gamete (ovum) and they together form a diploid cell, i.e, zygote is known as fertilisation.
Pollination and fertilization are interconnected. If there is no pollination then there will be no fusion of male and female gametes and then fertilization doesn't take place.
