Oophyte         
·noun Any plant of a proposed class or grand division (collectively termed oophytes or Oophyta), which have their sexual reproduction accomplished by motile antherozoids acting on oospheres, either while included in their oogonia or after exclusion.
Gametophyte         
·add. ·noun In the alternation of generations in plants, that generation or phase which bears sex organs. In the lower plants, as the algae, the gametophyte is the conspicuous part of the plant body; in mosses it is the so-called moss plant; in ferns it is reduced to a small, early perishing body; and in seed plants it is usually microscopic or rudimentary.
Gametophyte         
A gametophyte () is one of the two alternating multicellular phases in the life cycles of plants and algae. It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes.

Gametophyte

A gametophyte () is one of the two alternating multicellular phases in the life cycles of plants and algae. It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. The gametophyte is the sexual phase in the life cycle of plants and algae. It develops sex organs that produce gametes, haploid sex cells that participate in fertilization to form a diploid zygote which has a double set of chromosomes. Cell division of the zygote results in a new diploid multicellular organism, the second stage in the life cycle known as the sporophyte. The sporophyte can produce haploid spores by meiosis that on germination produce a new generation of gametophytes.
