Gametophyte is a dominant phase in the life cycle of a bryophyte. Explain.

Explanation

Gametophyte is a haploid multicellur adult stage in a bryophytes's life cycle. It bears male reproductive structure (antheridia) and female strurtrue called rchegonia, and thus produces hapliid gametes antherozoids (male gamete) and egg cell (female gamete ) respecitvely
In mosses, liverworts and hornworts the gametophye is a dominant form and thus most familiar phases of life cycle of the bryophyte. The moss gametophye originate from a haplod spore. Initial phase of grwoth forms protonema in moss.
The protonema further develops into a main plant body of bryophyte which is thallus like prostrate and erect, attached to substratum by unicellular or multicelluar rhizoids. They may possess root like leaf like or steam structures.
