Definition of Gametophyte Alternation of generations is a type of life cycle found in all plants and some algae species. This process involves a multicellular diploid generation called a sporophyte and a multicellular haploid generation called a gametophyte. Diploid means having two sets of chromosomes in your cells and is usually written as '2n'.
