Why gametophyte is dominant in baryophytes?

In bryophytes, the gametophyte generation is dominant because it is the stage that is more prominent, photosynthetic, and capable of independent growth. This generation develops from spores and produces gametes through mitosis, allowing for sexual reproduction and genetic diversity. The sporophyte, which arises from the fertilization of gametes, is typically dependent on the gametophyte for nutrition and support, making the gametophyte the more prominent and vital stage in the life cycle of bryophytes.
