WebTypical moss: green haploid body and brown diploid sporophyte. The term alternation of generations is used to describe an alternation of forms in the life cycle of plants (and some protists ). One form is diploid, with 2 n chromosomes: the sporophyte. The other form is haploid with only one set of chromosomes: the gametophyte. WebGoebel [1] termed the early stage of the development of the gametophyte and the sporophyte the ‘juvenile’ phase, and the later phase the ‘adult’ phase, and drew attention to the similarity between the juvenile-to-adult transition in plants and developmental transitions in animals, such as metamorphosis. Recent studies suggest that this similarity may …
