fertilization (Noun). The act or process of rendering fertile. fertilization (Noun). The act of fecundating or impregnating animal or vegetable gametes; esp., the process by which in flowers the pollen renders the ovule fertile, or an analogous process in flowerless plants; fecundation; impregnation.
Fertilisation (also known as conception, fecundation and syngamy) is the fusion of gametes to initiate the development of a new individual organism. In animals, the process involves the fusion of an ovum with a sperm, which first creates a zygote and then leads to the development of an embryo.llogamy, which is also known as cross-fertilization, refers to the fertilization of an egg cell from one individual with the male gamete of another. Autogamy which is also known as self-fertilization, occurs in such hermaphroditic organisms as plants and flatworms; therein, two gametes from one individual fuse.
