Alternation of generations - Wikipedia, the free encyclopedia
The Alternation of phases (or generations ) describes the life cycle of plants, fungi and protists. A multicellular diploid phase alternates with a multicellular haploid phase. The term can be con...

This is a diagram which demonstrates the biological concept of alternation of generations, specifically in ferns. This diagram is not to scale, nor is it necessarily anatomically accurate—it is designed as an aid in understanding the concept of alternation of gametophyte and sporophyte generations.
