Answer:
Gametophyte
Explanation:
This is is the dominant phase of moses (division bryophyte) and other lower plants such as pteridophytes and liverworts. The gametophytes produce haploid spores. When two diploid spores fuse into a zygote, it grows into a sporophyte, usually attached to a gametophyte, because it depends on it for water and nutrient. The sporophyte then produces haploid spores that give rise to gametophytes. The diploid phase is significant because it gives opportunity for recombination of genes which provides genetic variation among the moss.
