Explanation: 

Detailed explanation-1: -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. The complete series of this process takes place in the zygote to develop into a seed.

Detailed explanation-2: -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.

Detailed explanation-3: -Fertilisation: The fusion of a haploid male gamete (spermatozoa) and a haploid female gamete (ovum) to form a diploid cell, the zygote, is called fertilization.

Detailed explanation-4: -In a process called fertilisation, the two gametes join and their chromosomes combine, so that the fertilised cell contains a normal complement of chromosomes, with some from each parent flower.

Detailed explanation-5: -The process of fusion of sperm with egg (ovum) to produce a zygote is called fertilization.
