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

(N/A) $\rightarrow$ In the life cycle of bryophytes,the gametophytic stage is haploid and multicellular at the adult stage.
$\rightarrow$ It possesses male reproductive organs called $antheridia$ and female reproductive organs called $archegonia$,which produce haploid $antherozoids$ and female gametes,respectively.
$\rightarrow$ In mosses,liverworts,and hornworts,the gametophyte is the main dominant phase and is the most prominent stage in their life cycles. The gametophyte of mosses arises from haploid spores. The initial stage of a moss is the $protonema$.
$\rightarrow$ The $protonema$ develops into the main plant body (thallus) of the bryophyte. It is thalloid or prostrate/erect and is attached to the substratum by unicellular or multicellular $rhizoids$. They may possess root-like,stem-like,or leaf-like structures.
