How is a fern sporophyte different from a fern gametophyte?

In the life cycle of a fern, the sporophyte and gametophyte represent two distinct, alternating generations that differ significantly in structure, function, and genetic makeup.12

The Fern Sporophyte

The sporophyte is the dominant, asexual generation—the familiar plant typically recognized as a fern.12
* Structure: It consists of complex organs, including stems (often rhizomes), leaves (fronds), and roots.13
* Genetics: Its cells are diploid, containing two sets of chromosomes.12
* Function: It produces haploid spores via meiosis within specialized structures called sporangia.132

The Fern Gametophyte

The gametophyte, or prothallium, is the sexual, haploid generation.12
* Structure: It is typically a tiny, heart-shaped, independent structure, usually less than 8–13 mm in size, and is often only one cell layer thick. It lacks true roots, stems, or leaves, using rhizoids for attachment.1452
* Genetics: Its cells are haploid, containing only one set of chromosomes.1
* Function: It produces gametes (sperm and eggs) in organs called antheridia and archegonia. Following fertilization, the resulting zygote develops into a new sporophyte, after which the gametophyte typically withers and dies.521
