You really should look into plant and fungi alternation of generations ( which give interesting evolutionary clues ). 15. Like other ferns rattlesnake fern undergoes alternation of generations and the form described in this article is the sporophyte. 16. The red algal life history is typically an alternation of generations that may have three generations rather than two. 17. However, there are many possible variations on the fundamental elements of a life cycle which has alternation of generations . 18. In common with all groups of multicellular algae they have a life cycle which involves'alternation of generations '. 19. They cannot be grown by vegetative means, but must go through a reproductive cycle involving an alternation of generations . 20.
