Detailed explanation-1: -After fertilisation, a tiny plant called an embryo is formed inside a seed. The seed protects the embryo and stores food for it. The parent plant disperses or releases the seed. If the seed lands where the conditions are right, the embryo germinates and grows into a new plant.

Detailed explanation-2: -The process of fertilization in plants occurs when gametes in haploid conditions meet to create a zygote which is diploid. The male gametes of the flower are transferred on to the female reproductive organs through pollinators. The final product of this process is the formation of embryo in a seed.

Detailed explanation-3: -Answer : The function of a flower is to carry out sexual reproduction in plants through the formation of male and female gametes. Flowers ensure that the gametes fertilise to form seeds that further help in reproducing plants.

Detailed explanation-4: -In plants, fertilization is a process of sexual reproduction, which occurs after pollination and germination. Fertilization can be defined as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote. It is a physicochemical process which occurs after the pollination of the carpel.

Detailed explanation-5: -Fertilization: The fusion of male and female gamete to form a zygote is called fertilization. As a result of pollination, pollen grains are deposited on the stigma of the carpel, and it grows into a pollen tube. The Pollen tube pierces the stigma and grows through style.
