Gamete

Gametes, informally sex cells, are the mature haploid reproductive (germ) cells of higher organisms. The gametes of females are called eggs, the gametes of males are called sperm. When a sperm and an egg (normally of the same species) fuse, they form a zygote, a diploid cell that grows to a new organism, which carries half of the DNA of both father and mother.

Organs that produce gametes are called gonads in animals, or archegonia and antheridia[?] in plants.
