Thus in Pellia the nuclei of the gametophyte have eight chromosomes and those of the sporophyte sixteen.
The sporophyte may be considered to begin at the stage of nuclear association and end with the nuclear reduction in the basidium.
In contrast to the sexual generation this stage is called the spore-bearing generation (sporogonium, sporophyte).
H, sporophyte bearing the single sporangium on its upper surface.
Among organisms which display an alternation of generations (such as plants, fungi, and certain algae), the individual diploid organism that produces spores. A sporophyte develops from an embryo resulting from the union of two gametes. Each of its cells has two sets of chromosomes, as opposed to the haploid gametophyte generation.
