Culture definitions for fertilization
The joining of sex cells to form a new living thing. In humans, a male sperm joins a female ovum, or egg; the resulting zygote divides into a multicelled structure that implants in the womb and grows into an embryo. In plants, pollen grains, containing the male sex cells, enter the female sex cells in the pistil; from this union, fruit eventually grows. When fertilization occurs within a single flower, we call it self-fertilization. (See cross-fertilization.)
