Life Cycle

Alterations of Generations: The regular alternation of forms or of mode of reproduction in the life cycle of an organism, such as the alternation between diploid and haploid phases, or between sexual and asexual reproductive cycles.  It is a type of life cycle found in some algae, fungi, and all plants where an organism alternates between a haploid (n) gametophyte generation and a diploid (2n) sporophyte generation.  A diploid plant (sporophyte) produces, by meiosis, a spore that gives rise to a multicellular, haploid pollen grain (gametophyte).


Side Note: My babies didn't start out being my babies but over the course of about 8 weeks they have become my pride and joy. Its so hard to believe that they started out by going through meiosis, becoming spores, going through mitosis, then becoming gametes, getting fertilized and becoming a zygote and then they came to that agency and Jonah really helped me out with getting the best seeds.
