What is the major difference between moss and fern life cycle?

The main reason is that in moss' life cycle the gametophyte (that is the visible part of moss) is dominant, and in the fern's life cycle the sporophyte (that is the visible plant of fern) is dominant.

What is the major difference between moss and fern life cycle?
Their cycles are actually very much the same, so I'm not sure what you are looking for. The actual appearance of the plants is different, such as the spores on ferns are produced in sori under the leaves, while the spores on moss are produced on a stalk that sticks out from the moss. But other than appearance of the structures (gametophyte, sporophyte, archegonium, antheridium, etc), the cycles are basically the same.
