Liverworts

Vedclass · Answer

(A) In $Bryophytes$,the life cycle involves a gametophytic stage. In $Liverworts$ (like $Marchantia$),the spores germinate to produce a thalloid gametophyte directly. In contrast,in $Mosses$,the spores germinate to produce a filamentous stage called the $protonema$,which then develops into the leafy gametophyte. Therefore,the correct answer is $Liverworts$.

In $......$,spores do not form a protonema but grow directly into a flat,branched thallus.
