Bryophyte moss growing on oak trees.
In the life cycle of a bryophyte, the gametophyte stage is haploid.12
In the alternation of generations characteristic of land plants, the gametophyte generation possesses a single set of chromosomes (1n). This stage is the dominant, long-lived, and photosynthetically independent phase in bryophytes, such as mosses and liverworts. The gametophyte produces gametes (sperm and eggs) through mitosis, which then fuse during fertilization to form a diploid zygote, marking the beginning of the sporophyte generation.13245
