In the life cycle of a fern, there is an alternation of generations between a haploid gametophyte and a diploid sporophyte.
Diploid Nature: The sporophyte is the familiar, leafy fern plant and is diploid (2n) because it develops from a zygote formed by the fusion of two haploid gametes.
Independence: While the young sporophyte initially depends on the gametophyte for nutrition, it quickly develops its own roots and leaves, becoming photosynthetic and independent as the gametophyte eventually withers away. It is the dominant phase of the fern life cycle.
