Describe the adaptations of phloem tissue
WebThe evolution of vascular tissue for the distribution of water and solutes was a necessary prerequisite for plants to evolve larger bodies. The vascular system contains xylem and phloem tissues. Xylem conducts water and minerals taken from the soil up to the shoot; phloem transports food derived from photosynthesis throughout the entire plant. 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.
