Detailed explanation-1: -Fertilization between the haploid gametes forms a diploid zygote. The zygote will undergo many rounds of mitosis and give rise to a diploid multicellular plant called a sporophyte. Specialized cells of the sporophyte will undergo meiosis and produce haploid spores.

Detailed explanation-2: -Fertilization is the process in which haploid gametes fuse to form a diploid cell called a zygote.

Detailed explanation-3: -Through the process of fertilization, egg and sperm join to make a cell with 46 chromosomes (23 pairs), called a zygote.

Detailed explanation-4: -Fertilisation. The process of union of male and female gametes is called fertilisation.

Detailed explanation-5: -At fertilization, the sperm binds to a receptor on the surface of the egg and fuses with the egg plasma membrane, initiating the development of a new diploid organism containing genetic information derived from both parents (Figure 14.41).
