The expression alternation of generations refers to reproductive cycles that occur in different living organisms, such as those in terrestrial plants, including the occurrence of alternation of generations of terrestrial plants is a characteristic that does not occur in Charales.
The alternation of generations is a phenomenon present in the life cycle of all plants and also in some algae and fungi. This alternation means that during the life of the plant it will go through a haploid phase called the gametophyte, which will alternate with the diploid generation known as the sporophyte. A haploid cell has only one set of chromosomes (n), while a diploid cell has two sets (2n).
