a means of supporting structures against gravity

a set of pigments that allowed them to photosynthesize out of water

Explanation / Answer
The current reference to the first land plants, like mosses and ferns, still need the water to reproduce, are prone to drying out (live in semi-aquatic environments) and present pigments photosynthetics. Therefore, the evolutionary novelty presented by the first terrestrial plants were the support structures, the accumulation of cellulose to thicken the cell walls and later the generation of wood in higher plants.
