In plant alternation of generations, which processes alternate?

Explanation:
In plant alternation of generations, the life cycle shifts between a diploid sporophyte and a haploid gametophyte. The transitions between these generations are driven by meiosis and fertilization. Meiosis happens in the sporophyte to produce haploid spores, which develop by mitosis into the haploid gametophyte. The gametophyte then makes gametes by mitosis, and fertilization fuses two gametes to form a diploid zygote, which grows into a new sporophyte. So the processes that alternate between generations are meiosis and fertilization. Mitosis occurs within each generation to grow tissues but does not switch the ploidy level between generations.
