Yes, in ferns, the sporophyte generation is dominant and produces spores that give rise to the gametophyte generation. The gametophyte generation is a smaller, independent stage that produces gametes (sperm and egg) which fuse during fertilization to form the sporophyte generation.
In most plants, the sporophyte generation is dominant. In fern, for example, the fern itself is the sporophyte. This organism produces spores that fall to the substrate below and grow into a separate organism called a gametophyte. The gametophyte produces sperm and eggs in order to produce a new sporophyte which grows out of the gametophyte's body, destroying it. It is important to note that the gametophyte is haploid and the sporophyte is dploid.
Sorus is a structure found on the underside of fern leaves that contains the sporangia, which produce spores. The spores give rise to the gametophyte generation in ferns.
Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle. The plants which we call mosses and ferns are the gametophyte generations. However conifers and flowering plants are the sporophyte generation of their life cycle. This is much easier to understand if you see a diagram.
The life cycle of nonvascular plants includes an alternation of generations between a gametophyte and a sporophyte. The gametophyte generation produces gametes (eggs and sperm) through mitosis, which then fuse to form a zygote that develops into the sporophyte generation through mitosis. The sporophyte produces spores through meiosis that develop into new gametophytes.
What is the process that occurs before the gametophyte generation Edited answer: Sporogenesis in the sporophyte is the starting point for gametophytic generation to produce haploid spores.

Sporophyte is the diploid (2n) stage in the life cycle of plants that produces spores through meiosis, while gametophyte is the haploid (n) stage that produces gametes through mitosis. Sporophyte generation is dominant in vascular plants, while gametophyte generation is dominant in non-vascular plants like mosses and liverworts.

The seta and capsule are known as the sporophyte generation because they are structures that produce spores through meiosis, which will ultimately give rise to the gametophyte generation. The sporophyte generation is diploid, meaning it contains two sets of chromosomes, whereas the gametophyte generation is haploid, containing one set of chromosomes.
Alteration of generations Sporophyte is 2n generation Meiosis produces spores Gametophyte is n generation
The dominant generation of division Cycadophyta is the sporophyte generation. This generation is the main phase of the plant's life cycle and produces spores that give rise to the next generation of plants. The sporophyte is typically larger and longer-lived than the gametophyte generation.
The dominant generation in the life cycle of ferns is the sporophyte, which is the plant that produces spores. The sporophyte is the visible, leafy plant that we typically think of as a fern. It plays a crucial role in reproduction by producing spores that develop into the gametophyte, which is a smaller, less visible plant that produces eggs and sperm. The gametophyte then fertilizes and develops into a new sporophyte, completing the life cycle of ferns.
