Impregnation :: Impregnation (n.) The fusion of a female germ cell (ovum) with a male germ cell (in animals, a spermatozoon) to form a single new cell endowed with the power of developing into a new individual; fertilization; fecundation..

Fecundation :: Fecundation (n.) The act by which, either in animals or plants, material prepared by the generative organs the female organism is brought in contact with matter from the organs of the male, so that a new organism results; impregnation; fertilization..

Parthenogenesis :: Parthenogenesis (n.) The production of seed without fertilization, believed to occur through the nonsexual formation of an embryo extraneous to the embrionic vesicle..

Self-fertilization :: Self-fertilization (n.) The fertilization of a flower by pollen from the same flower and without outer aid; autogamy.

Geitonogamy :: Geitonogamy (n.) Fertilization of flowers by pollen from other flowers on the same plant.
