difference between pollination and fertilisation
Answers
Answer: The process of transfer of pollen from the male parts (anther) of a flower to the female part (stigma) of the same or different flower is called as pollination. Whereas the fertilization is the common process, involving the union of the male gamete (sperm) and female gamete (egg).
Pollination does not involve the formation of the pollen tube, while in fertilization there is the formation of pollen tube which helps in transferring of male gametes up to an egg cell.
Pollination is an external mechanism and takes place on an outer part of a flower, while fertilization is an internal mechanism and takes place inside the flowers.
Pollination takes place before fertilization, and it is of two types – self-pollination and cross-pollination. Fertilization takes place only after pollination.
Pollination occurs in flowering plants only, and fertilization is followed by almost every living plants and living being present on earth.
Pollination requires pollinating agent like wind, insects, animals, etc., whereas in fertilization there is no such requirement apart from the male gamete (sperms) and female gamete (egg).
