Gametophyte is the gamete-bearing individual or phase in the life cycle of a plant having alternation of generations. It is the haploid phase which produces gametes by mitosis in order to produce a zygote (from which the sporophyte arises). It is the dominant form in certain plants like bryophytes.
Sporophyte on the other hand is the asexual and usually diploid phase, producing spores (by meiosis) from which the gametophyte arises. It is the dominant form in vascular plants.
