A
gametophyte is the
haploid state of life of a sexually reproducing
plant. The gametophyte can be the dominant part of the life cycle as in
moss, or very reduced as in
angiosperms (flowering plants), where the female form (
egg sac[?]) is known as a
megagametophyte and the male form (
pollen) is called a
microgametophyte.
