A '''gamete''' is a reproductive cell of an animal or plant. In animals, female gametes are called ova or egg cells, and male gametes are called sperm. Ova and sperm are [[Haploid cells|haploid cells]], with each cell carrying only one copy of each chromosome. During fertilization, a sperm and ovum unite to form a new [[Diploid organism|diploid organism]]. | A '''gamete''' is a reproductive cell of an animal or plant.

In the male, the production of mature sperm cells, or spermatogenesis, results in four haploid gametes, whereas, in the female, the production of a mature egg cell, oogenesis, results in just one mature gamete. | Human sperm and eggs contain 23 chromosomes. Human zygotes contain 46 chromosomes. | ||
