Gametophyte
The cells from the male and female that combine to form a zygote are called gametes. The main job of the gametophyte is gamete production. Gametes are haploid reproductive cells. Gametes are produced in the sex organs on the haploid gametophyte by mitosis or cellular division without reduction of chromosomes sets.
