Solution
The correct option is D A-4, B-3, C-1, D-2
The correct answer is D.A median longitudinal furrow or depression is present on the dorsal surface of Riccia.
The gametophyte of Marchantia is a dichotomously branched, prostrate, dorsiventral thallus. 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.
In Anthoceros the lower ventral surface bears numerous unicellular, smooth walled rhizoids along the median line. Tuberculate rhizoids, scales or mucilage hairs are absent in Anthoceros.
Funaria has a height of 3–5 cm, a radial symmetry with a differentiation of an axis or stem, leaves or phylloids are multicellular colorless branched rhizoids with oblique septa. These are primitive multicellular, autotrophic, shade loving, amphibious plants. They reproduce by spore formation.
