Explanation:

The fern belong to phylum pteridophyta. These are non-flowering plants and include all types of ferns. They exhibit distinct alternation of generation with the gametophyte and sporophyte. The sporophyte is the larger dorminant plants having a simple shoot and root system. It produces male and female sex cells. The male gamete is flagellated and swims to the ovum and fertilizes it. The ferns are dependent on water in order to complete their life cycle.
