Marchantia is an example of Liverwort. The Marchantia is having elongated and elaborated archegoniophores. The gametangia are attached to the fleshy receptacle and it is attached to the elongated stalk from the surface of the gametophyte. The archegonia hang from the underside of the receptacle. During the process of fertilization sperm swims to the egg through the venter of the archegonium; the process of syngamy occurs. The zygote is formed in the venter of the archegonium which later forms the sporophyte. The sporophyte is parasitic with haustorial foot, a stalk and the sporogonium.
