The spore bearing, asexual generation of a plant is known as the sporophyte generation. This is the 2n, or diploid generation that produces haploid spores. Pictured below is a perfect example of a sporophyte, a fern. Contained under the leaves of this fern are the spores it produces through meiosis. The spores will then form the next generation of fern, but before becoming the sporophyte pictured below, it becomes the gametophyte. A fern spends the majority of it’s life cycle as a diploid sporophyte, and a smaller portion of the time as a haploid gametophyte. It’s the gametophyte that eventually turns into the sporophyte, what we see as the fern plant. Vascular plants tend to have a dominant sporophyte generation while nonvascular plants have a dominant gametophyte generation.
