Question

what is fertilisation?

Answer 1

Fertilisation or fertilization (see spelling differences), also known as generative fertilisation, insemination, pollination,[1]fecundation, syngamy and impregnation,[2]is the fusion of gametes to initiate the development of a new individual organism.[3]The cycle of fertilisation and development of new individuals is called sexual reproduction. During double fertilisation in angiosperms the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative fertilisation.
