Liverworts (Hepaticophyta) are viewed as the plants most closely related to the ancestor that moved to land. The vascular tissue includes the xylem, which transports water, and the phloem, which transports sugars from the source (where they are made) to sink (where they are used). 2. How does the removal of such large numbers of trees from the world's forests affect the concentration of carbon dioxide in the atmosphere? Will you pass the quiz? Despite not having these tissues, they have other simpler structures for water transport. Individual results may vary. Vascular tissue present, pollen, naked seeds produced in cones, can produce wood, stems, leaves, roots. The answer is simple, non-vascular plants have other simpler structures for transporting water, also called poikilohydrics .
