Define alternation of genetations
An organism has two distinct life stages; a diploid sporophyte and a haploid gametophyte generation. - The sporophyte generation, through meiosis, produces spores that develop into the gametophyte generation.
- The gametophyte generation, through mitosis, produces gametes (eggs and sperm) that fuse (fertilization) and develop into the sporophyte generation.
