Answer: 1. The spores produced by moss sporophytes are produced by meiosis. Production of gametes involves mitosis. Mature gametes fuse to produce the zygote which is diploid (2n). This zygote now further divides by meiosis which leads to the production of spores which are haploid (n). This process occurs in the sporophyte stage of the moss plant.
2. Spores belong to the gametophyte stage of the life cycle of moss. The gametophyte stage starts with the spores. These spores lead to the development of male and female gametes which fuse to form the zygote which eventually leads to the onset of the sporophytic stage. This is also known as alternation of generation.
