Gam"ete (găm"&ē;t; g&adot_;*m&ē;t"; the latter usually in compounds), n. [Gr. gameth` wife, or game`ths husband, fr. gamei^n to marry.] (Biol.) A sexual cell or germ cell having a single set of unpaired chromosomes; a conjugating cell which unites with another of like or unlike character to form a new individual. In Bot., gamete designates esp. the similar sex cells of the lower thallophytes which unite by conjugation, forming a zygospore. The gametes of higher plants are of two sorts, sperm (male) and egg (female); their union is called fertilization, and the resulting zygote an o&ö;spore. In Zo&ö;l., gamete is most commonly used of the sexual cells of certain Protozoa, though also extended to the germ cells of higher forms.
