A sporophyte is the structure of plant or alga that has a diploid set of chromosomes. It is seen in all plants and in some algae.

The Sporophyte Generation
The plant we recognize as a fern is the diploid sporophyte generation.

of generations in all plants.) ...

Rabe and Haufler (1992) found a naturally occurring diploid sporophyte of maidenhair fern which produced unreduced (2N) spores. These spores resulted from a failure of the paired chromosomes to dissociate during the first division of meiosis.
Full article >>>

This involves an alternation between two generations: a haploid stage, called the gametophyte, and a diploid stage, called the sporophyte. The sporophyte is short-lived and remains dependent on its parent.
