Hello buddy..
The gametophyte of Marchantia is a dichotomously branched, prostrate, dorsiventral thallus (Fig. 6.8). The dorsal surface of the thallus shows many regular rhomboidal or polygonal areas . Each area has a pore at the center.
A distinct median groove (midrib) is present on the upper (dorsal) surface in each branch of the thallus with a corresponding ridge on the ventral surface. The branches grow indefinitely by means of a growing point situated in the terminal groove (apical notch).
The ventral surface of the thallus bears three to four rows of scales and rhizoids on both sides of the mabrid
The sexually mature thalli bear specialised erect branches called gametophores or gametan- giophores which bear sex organs. These branches are umbrella shaped and arises from the apical notch.
Hope it helps you..
