What capability did the development of a vascular system provide to plants? Greater efficiency for nutrient transport and structural support What is the same and what is different between gymnosperms and angiosperms?
Nutrient, Liquid and Energy Distribution. Most of the advantages of vascular tissues stem from this functional one: A tracheophyte's xylem and phloem--which comprise the vascular system and are housed in the stem--enable liquids, nutrients and energy to be transported and distributed throughout the whole of the plant.
