What makes land plants unique 2) Walled spores produced in sporangia Sporopollenin in walls - Bryophyte – a collective term for the liverworts, hornworts and mosses. Evolutionary significance of bryophytes. Vascular plants, particularly seed plants, dominate vegetation throughout much of the world today, from the lush rainforests of the tropics harbouring a vast diversity of angiosperms, to the boreal forests of coniferous trees, draping the northern latitudes of the globe.

Vascular plants, particularly seed plants, dominate vegetation throughout much of the world today, from the lush rainforests of the tropics harbouring a vast diversity of angiosperms, to the boreal forests of coniferous trees, draping the northern latitudes of the globe. Evolution of Sporophyte in Bryophytes: The sporophyte of bryophytes is called sporogonium which generally consists of a sin­gle, terminal sporangium (monosporangiate) with a bulbous foot and with or without an unbranched stalk or seta. The sporogonium is very delicate, short-lived and nutritionally dependent on its gametophyte. There are two theories regarding Evolution of Bryophytes: (i) The first theory is known as up-grade or progressive evolution theory, (ii) and the second one is called down-grade or regressive evolution theory. According to these theories the evolution in bryophytes is as follows. EVOLUTION OF LAND PLANTS. From Last Day: Closest Living Relatives of Land Plants - Charophytes. Sporophyte.
