What is fertilization?​

Answer 1

Answer:

Fertilization can be defined as the union of two haploid gametes, the spermatozoa and the oocyte, hereto referred to as egg, to restore the diploid state, form a zygote through the process of egg activation, and commence a series of mitotic divisions that results in cell differentiation and embryo development..

Answer 2

Answer:

Fertilisation or fertilization (see spelling differences), also known as generative fertilisation, syngamy and impregnation,[1] is the fusion of gametes to give rise to a new individual organism or offspring and initiate its development. Processes such as insemination or pollination which happen before the fusion of gametes are also sometimes informally called fertilisation.[2] 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.
