Gametophyte
From Wacklepedia - The Free Encyclopedia
A
gametophyte is the
haploid state of life of a sexually reproducing
plant. Each cell of the gametophyte phase contains one complete set of
chromosomes. The gametophyte can be the dominant part of the life cycle as in mosses, or very reduced as in
angiosperms (flowering plants), where the female form (
ovule) is known as a
megagametophyte and the male form (
pollen) is called a
microgametophyte.
