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. There are
two sex organs; archegonium which is found in the female sex organ
producing egg cell and antheridium which is found in the male sex organ
producing sperm cells.
