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.
Fertilization in advanced plants is preceded by pollination, during which pollen is transferred to, and establishes contact with, the female gamete or macrospore. Fusion in advanced animals is usually followed by penetration of the egg by a single spermatozoon.
