Review sheet: BIG TREES Tudge How do algae, mosses and ferns relate to the evolution of land plants? The first land plants were algae. They were unicellular and did not have an upright stem and could not avoid dring and also had no support against gravity. They gave rise to mosseswhich had short stems, but no way to transport water up the stems. Moss gave rise to ferns which were the first vascular plants- they were able to move water up the stem.
