Gametophyte

A gametophyte is the haploid state of life of a sexually reproducing plant. Each cell contains a complete set of chromosomes. 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.
