Gametophyte is a dominant phase in the life cycle of a bryophyte. Explain.
The gametophyte is a haploid multicellular adult stage in a bryophyte's life cycle. It bears male reproductive structure (antheridia) and a female reproductive structure called archegonia, and thus produce haploid gametes antherozoids (male gamete) and egg cell (female gamete) respectively.
In mosses, liverworts and hornworts the gametophyte is a dominant form and thus the most familiar phase of the life cycle of the bryophyte. The moss gametophyte originates from a haploid spore. The initial phase of growth forms protonema in moss.
The protonema further develops into the main plant body of bryophyte which is thallus like prostrate and erect, attached to the substratum by unicellular or multicellular rhizoids. They may possess root-like, leaf-like or stem-like structures.
