WebThe two primary vascular tissues are xylem, which transports water and dissolved minerals from the roots to the leaves, and phloem, which conducts food from the leaves to all parts of the plant. Most extant plants on Earth have vascular systems, including the lower vascular plants ( lycophytes and ferns ), gymnosperms, and angiosperms. WebPlants have transport systems to move food, water and minerals around. These systems use continuous tubes called xylem and phloem: - Xylem vessels carry water and minerals from the roots to the leaves. - Phloem tubes carry sugar & other organic nutrients made by plant from the leaves to the rest of the plant.
