Answer:
Gametophyte
Step-by-step explanation:
Moss is among the most famous species of bryophytes.
Bryophytes do not have sap-conducting vessels (they have no xylem or phloem), and their dominant phase is the gametophyte, which is the haploid (n) phase of the life cycle responsible for gamete production.
In bryophytes, gametophytes generally have separate sexes. Male gametophytes produce mobile gametes with flagella, called anterozoids. Female gametophytes, on the other hand, produce immobile gametes called oospheres.
Once produced in the male plant, anterozoids can be taken to a female plant with falling and splashing rainwater.
