Gametophyte - Wikipedia
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.

The gametophyte is a stage in the life cycle that is found in all plants and certain species of algae. This process includes both multicellular diploid generation known as Sporophyte and a multicellular haploid generation known as Gametophyte. The word Diploid refers to two sets of chromosomes in the cells, and normally written as ‘2n’.

2002年10月29日 · The first gametophytic division is asymmetric, producing one large and one small cell. In C. richardii, the large cell divides again asymmetrically to produce another small cell, which later develops into the rhizoid, a root-like structure. The small cell from the first division becomes the protonemal initial, which divides further to form a ...
