Difference Between Pollination And Fertilisation
Pollination is defined as the transfer of pollen grains from the anthers to the stigma. Fertilisation is the fusion of the nuclei of two dissimilar male and female gametes.
Pollination results in germination of pollen grains, formation of pollen tubes and entry of pollen tube inside the ovary to the ovules. And fertilisation results in the formation of zygote and subsequently seeds.
In flowering plants, fertilization is known as double fertilization because two male nuclei from the pollen grain fuses with the egg and polar nuclei and forms diploid zygote and triploid endosperm respectively.
The pollen nucleus fuses that with egg nucleus forms zygote that develops into an embryo and then to a sporophyte.
The other pollen nucleus combines with two nuclei in the female gametophyte and forms triploid nucleus. It develops into a triploid tissue called as endosperm. Endosperm nourishes the developing embryo of plant.
Difference Between Pollination And Fertilisation
1) Pollination is defined as the transfer of pollen grains from the anthers (male part) to the stigma (female part). The flower is reproductive part of plant in which male parts known as stamens and are made of anther. The female parts known as pistil and the top of the pistil is called as stigma. Stigma is known to have sticky surface to receive and stick the pollen.
Fertilisation is defined as fusion of the nuclei of male and female gametes.
2) Pollination results in pollen grains germination, pollen tubes formation and pollen tube entry inside the ovary to the ovules.
Fertilisation results in the formation of zygote and seeds.
3) Pollination is a physical process, which means new substance is not formed.
Fertilization is biological process in which new substance called zygote is formed.
